Enum std::num::FpCategory 1.0.0
[−]
[src]
pub enum FpCategory {
Nan,
Infinite,
Zero,
Subnormal,
Normal,
}A classification of floating point numbers.
This enum is used as the return type for f32::classify and f64::classify. See
their documentation for more.
Examples
use std::num::FpCategory; use std::f32; let num = 12.4_f32; let inf = f32::INFINITY; let zero = 0f32; let sub: f32 = 1.1754942e-38; let nan = f32::NAN; assert_eq!(num.classify(), FpCategory::Normal); assert_eq!(inf.classify(), FpCategory::Infinite); assert_eq!(zero.classify(), FpCategory::Zero); assert_eq!(nan.classify(), FpCategory::Nan); assert_eq!(sub.classify(), FpCategory::Subnormal);Run
Variants
Nan"Not a Number", often obtained by dividing by zero.
InfinitePositive or negative infinity.
ZeroPositive or negative zero.
SubnormalDe-normalized floating point representation (less precise than Normal).
NormalA regular floating point number.
