# Enum std::num::FpCategory [−] [src]

    pub enum FpCategory {
        Nan,
        Infinite,
        Zero,
        Subnormal,
        Normal,
    }

1.0.0

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.

## Variants

`Nan` | "Not a Number", often obtained by dividing by zero |
`Infinite` | Positive or negative infinity |
`Zero` | Positive or negative zero |
`Subnormal` | De-normalized floating point representation (less precise than `Normal`) |
`Normal` | A regular floating point number |

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
