Constant core::f64::EPSILON

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

👎Deprecating in a future Rust version: replaced by the EPSILON associated constant on f64

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;
