Constant core::f64::NAN

pub const NAN: f64 = f64::NAN; // NaNf64

👎 Deprecating in a future Rust version:

replaced by the NAN associated constant on f64

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

Not a Number (NaN). Use f64::NAN instead.

Examples

// deprecated way
let nan = std::f64::NAN;

// intended way
let nan = f64::NAN;
