Primitive Type f64 

A 64-bit floating-point type (specifically, the “binary64” type defined in IEEE 754-2008).

This type is very similar to f32, but has increased precision by using twice as many bits. Please see the documentation for f32 or Wikipedia on double-precision values for more information.

See also the std::f64::consts module.
