# Constant core::f64::NEG_INFINITY 1.0.0[−][src]

    pub const NEG_INFINITY: f64 = f64::NEG_INFINITY; // -Inff64

👎 Deprecating in a future Rust version:

replaced by the `NEG_INFINITY` associated constant on `f64`

Negative infinity (−∞). Use `f64::NEG_INFINITY` instead.

# Examples

    // deprecated way
    let ninf = std::f64::NEG_INFINITY;

    // intended way
    let ninf = f64::NEG_INFINITY;
