# Constant EPSILON

1.6.0 · Source

    pub const EPSILON: f64 = f64::EPSILON; // 2.2204460492503131E-16f64

👎Deprecating in a future version: replaced by the `EPSILON` associated constant on `f64`
Expand description

Machine epsilon value for `f64`. Use `f64::EPSILON` instead.

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

## §Examples

    // deprecated way
    let e = std::f64::EPSILON;

    // intended way
    let e = f64::EPSILON;
