# Constant core::f32::NAN
1.0.0[−][src]

    pub const NAN: f32 = f32::NAN; // NaNf32

👎 Deprecating in a future Rust version:

replaced by the `NAN` associated constant on `f32`

This is supported on non-crate feature `miri-test-libstd` or `test` or `doctest` only.
Expand description

Not a Number (NaN). Use `f32::NAN` instead.

## Examples

    // deprecated way
    let nan = std::f32::NAN;

    // intended way
    let nan = f32::NAN;
