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

    pub const EPSILON: f32 = f32::EPSILON; // 1.1920929E-7f32

👎 Deprecating in a future Rust version:

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

Expand description

Machine epsilon value for `f32`. Use `f32::EPSILON` instead.

This is the difference between `1.0` and the next larger representable number.

## Examples

    // deprecated way
    let e = std::f32::EPSILON;

    // intended way
    let e = f32::EPSILON;
