pub const fn wrapping_div(self, rhs: i128) -> i128

Wrapping (modular) division. Computes self / rhs, wrapping around at the boundary of the type.

The only case where such wrapping can occur is when one divides MIN / -1 on a signed type (where MIN is the negative minimal value for the type); this is equivalent to -MIN, a positive value that is too large to represent in the type. In such a case, this function returns MIN itself.

Panics

Examples

Basic usage:

pub const fn wrapping_shl(self, rhs: u32) -> i128

Panic-free bitwise shift-left; yields self << mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_left function, which may be what you want instead.

Examples

Basic usage:

assert_eq!((-1i128).wrapping_shl(7), -128);
assert_eq!((-1i128).wrapping_shl(128), -1);

pub const fn wrapping_shr(self, rhs: u32) -> i128

Panic-free bitwise shift-right; yields self >> mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-right; the RHS of a wrapping shift-right is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_right function, which may be what you want instead.

Examples

Basic usage:

assert_eq!(100i128.wrapping_abs(), 100);
assert_eq!((-100i128).wrapping_abs(), 100);
assert_eq!(i128::MIN.wrapping_abs(), i128::MIN);

🔬This is a nightly-only experimental API. (bigint_helper_methods #85532)

Calculates self + rhs + carry and checks for overflow.

Performs “ternary addition” of two integer operands and a carry-in bit, and returns a tuple of the sum along with a boolean indicating whether an arithmetic overflow would occur. On overflow, the wrapped value is returned.

This allows chaining together multiple additions to create a wider addition, and can be useful for bignum addition. This method should only be used for the most significant word; for the less significant words the unsigned method u128::carrying_add should be used.

The output boolean returned by this method is not a carry flag, and should not be added to a more significant word.

If the input carry is false, this method is equivalent to overflowing_add.

Examples

// Only the most significant word is signed.
//
//   10  MAX    (a = 10 × 2^128 + 2^128 - 1)

🔬This is a nightly-only experimental API. (bigint_helper_methods #85532)

Calculates self − rhs − borrow and checks for overflow.

Performs “ternary subtraction” by subtracting both an integer operand and a borrow-in bit from self, and returns a tuple of the difference along with a boolean indicating whether an arithmetic overflow would occur. On overflow, the wrapped value is returned.

This allows chaining together multiple subtractions to create a wider subtraction, and can be useful for bignum subtraction. This method should only be used for the most significant word; for the less significant words the unsigned method u128::borrowing_sub should be used.

The output boolean returned by this method is not a borrow flag, and should not be subtracted from a more significant word.

If the input borrow is false, this method is equivalent to overflowing_sub.

Examples

#![feature(bigint_helper_methods)]
// Only the most significant word is signed.
//
//    6    8    (a = 6 × 2^128 + 8)
// - -5    9    (b = -5 × 2^128 + 9)
// ---------
//   10  MAX    (diff = 10 × 2^128 + 2^128 - 1)

If self > 0, this is equal to rounding towards zero (the default in Rust); if self < 0, this is equal to rounding away from zero (towards +/- infinity). If rhs > 0, this is equal to rounding towards -infinity; if rhs < 0, this is equal to rounding towards +infinity.

Panics

This function will panic if rhs is 0 or if self is Self::MIN and rhs is -1. This behavior is not affected by the overflow-checks flag.

Examples

Basic usage:

assert_eq!((-a).div_euclid(b), -2); // -7 >= 4 * -2

pub const fn rem_euclid(self, rhs: i128) -> i128

This is done as if by the Euclidean division algorithm – given r = self.rem_euclid(rhs), the result satisfies self = rhs * self.div_euclid(rhs) + r and 0 <= r < abs(rhs).

Panics

This function will panic if rhs is 0 or if self is Self::MIN and rhs is -1. This behavior is not affected by the overflow-checks flag.

Examples

Basic usage:

let a: i128 = 7; // or any other integer type
let b = 4;

assert_eq!((-a).rem_euclid(b), 1);

pub const fn checked_next_multiple_of(self, rhs: i128) -> Option<i128>

🔬This is a nightly-only experimental API. (int_roundings #88581)

If rhs is positive, calculates the smallest value greater than or equal to self that is a multiple of rhs. If rhs is negative, calculates the largest value less than or equal to self that is a multiple of rhs. Returns None if rhs is zero or the operation would result in overflow.

Examples

Basic usage:

#![feature(int_roundings)]
assert_eq!(16_i128.checked_next_multiple_of(8), Some(16));
assert_eq!(23_i128.checked_next_multiple_of(8), Some(24));
assert_eq!(16_i128.checked_next_multiple_of(-8), Some(16));
assert_eq!(23_i128.checked_next_multiple_of(-8), Some(16));

assert_eq!(i128::MAX.checked_next_multiple_of(2), None);

pub const fn ilog(self, base: i128) -> u32

Returns the logarithm of the number with respect to an arbitrary base, rounded down.

This method might not be optimized owing to implementation details; ilog2 can produce results more efficiently for base 2, and ilog10 can produce results more efficiently for base 10.

Panics

This function will panic if self is less than or equal to zero, or if base is less than 2.

Examples

assert_eq!(5i128.ilog(5), 1);

pub const fn ilog2(self) -> u32

Returns the base 2 logarithm of the number, rounded down.

Panics

This function will panic if self is less than or equal to zero.

Examples

assert_eq!(2i128.ilog2(), 1);

pub const fn ilog10(self) -> u32

Returns the base 10 logarithm of the number, rounded down.

Panics

This function will panic if self is less than or equal to zero.

Example

assert_eq!(10i128.ilog10(), 1);

pub const fn checked_ilog(self, base: i128) -> Option<u32>

Returns the logarithm of the number with respect to an arbitrary base, rounded down.

Returns None if the number is negative or zero, or if the base is not at least 2.

This method might not be optimized owing to implementation details; checked_ilog2 can produce results more efficiently for base 2, and checked_ilog10 can produce results more efficiently for base 10.

Examples

assert_eq!(5i128.checked_ilog(5), Some(1));

pub const fn checked_ilog2(self) -> Option<u32>

Returns the base 2 logarithm of the number, rounded down.

Returns None if the number is negative or zero.

Example

assert_eq!(10i128.checked_ilog10(), Some(1));

pub const fn abs(self) -> i128

Computes the absolute value of self.

Overflow behavior

The absolute value of i128::MIN cannot be represented as an i128, and attempting to calculate it will cause an overflow. This means that code in debug mode will trigger a panic on this case and optimized code will return i128::MIN without a panic. If you do not want this behavior, consider using unsigned_abs instead.

Examples

Basic usage:

assert_eq!(10i128.abs(), 10);
assert_eq!((-10i128).abs(), 10);

pub const fn abs_diff(self, other: i128) -> u128

Computes the absolute difference between self and other.

This function always returns the correct answer without overflow or panics by returning an unsigned integer.

Examples

Basic usage:

assert_eq!(100i128.abs_diff(80), 20u128);
assert_eq!(100i128.abs_diff(110), 10u128);
assert_eq!((-100i128).abs_diff(80), 180u128);
assert_eq!((-100i128).abs_diff(-120), 20u128);
assert_eq!(i128::MIN.abs_diff(i128::MAX), u128::MAX);

pub const fn signum(self) -> i128

Returns a number representing sign of self.

• 0 if the number is zero
• 1 if the number is positive
• -1 if the number is negative

Examples

Basic usage:

assert_eq!(10i128.signum(), 1);
assert_eq!(0i128.signum(), 0);
assert_eq!((-10i128).signum(), -1);

pub const fn is_positive(self) -> bool

assert_eq!(bytes, [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56, 0x78, 0x90, 0x12]);

pub const fn to_le_bytes(self) -> [u8; 16]

Returns the memory representation of this integer as a byte array in little-endian byte order.

Examples

assert_eq!(bytes, [0x12, 0x90, 0x78, 0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12]);

pub const fn to_ne_bytes(self) -> [u8; 16]

Returns the memory representation of this integer as a byte array in native byte order.

As the target platform’s native endianness is used, portable code should use to_be_bytes or to_le_bytes, as appropriate, instead.

Examples

let bytes = 0x12345678901234567890123456789012i128.to_ne_bytes();

    }
);

pub const fn from_be_bytes(bytes: [u8; 16]) -> i128

Creates an integer value from its representation as a byte array in big endian.

Examples

assert_eq!(value, 0x12345678901234567890123456789012);

When starting from a slice rather than an array, fallible conversion APIs can be used:

    let (int_bytes, rest) = input.split_at(std::mem::size_of::<i128>());
    *input = rest;

    *input = rest;
    i128::from_le_bytes(int_bytes.try_into().unwrap())
}

pub const fn from_ne_bytes(bytes: [u8; 16]) -> i128

Creates an integer value from its memory representation as a byte array in native endianness.

As the target platform’s native endianness is used, portable code likely wants to use from_be_bytes or from_le_bytes, as appropriate instead.

Examples

let value = i128::from_ne_bytes(if cfg!(target_endian = "big") {
    [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56, 0x78, 0x90, 0x12]

}

pub const fn min_value() -> i128

👎Deprecating in a future version: replaced by the MIN associated constant on this type

New code should prefer to use i128::MIN instead.

Returns the smallest value that can be represented by this integer type.

pub const fn max_value() -> i128

👎Deprecating in a future version: replaced by the MAX associated constant on this type

New code should prefer to use i128::MAX instead.

Returns the largest value that can be represented by this integer type.

pub const fn midpoint(self, rhs: i128) -> i128

🔬This is a nightly-only experimental API. (num_midpoint #110840)

Calculates the middle point of self and rhs.

midpoint(a, b) is (a + b) / 2 as if it were performed in a sufficiently-large signed integral type. This implies that the result is always rounded towards zero and that no overflow will ever occur.

Examples

#![feature(num_midpoint)]
assert_eq!(0i128.midpoint(4), 2);
assert_eq!((-1i128).midpoint(2), 0);
assert_eq!((-7i128).midpoint(0), -3);
assert_eq!(0i128.midpoint(-7), -3);
assert_eq!(0i128.midpoint(7), 3);

impl i128

pub const fn from_str_radix( src: &str, radix: u32, ) -> Result<i128, ParseIntError>

Converts a string slice in a given base to an integer.

The string is expected to be an optional + or - sign followed by only digits. Leading and trailing non-digit characters (including whitespace) represent an error. Underscores (which are accepted in rust literals) also represent an error.

Digits are a subset of these characters, depending on radix:

• 0-9
• a-z
• A-Z

Panics

This function panics if radix is not in the range from 2 to 36.

Examples

Basic usage:

assert_eq!(i128::from_str_radix("A", 16), Ok(10));

Trailing space returns error:

assert!(i128::from_str_radix("1 ", 10).is_err());
