Enum concordium_std::num::FpCategory 1.0.0[−][src]
pub enum FpCategory { Nan, Infinite, Zero, Subnormal, Normal, }
Expand description
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; 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);
Variants
Expand description
“Not a Number”, often obtained by dividing by zero.
Expand description
Positive or negative infinity.
Expand description
Positive or negative zero.
Expand description
De-normalized floating point representation (less precise than Normal
).
Expand description
A regular floating point number.
