Primitive Type f128

🔬This is a nightly-only experimental API. (f128 #116909)

A 128-bit floating point type (specifically, the “binary128” type defined in IEEE 754-2008).

This type is very similar to f32 and f64, but has increased precision by using twice as many bits as f64. Please see [the documentation for f32 or Wikipedia on quad-precision values for more information.

See also the std::f128::consts module.
