pub const fn maximumf64(x: f64, y: f64) -> f64🔬This is a nightly-only experimental API. (
core_intrinsics)Expand description
Returns the maximum of two f64 values, propagating NaN.
This behaves like IEEE 754-2019 maximum. In particular: If one of the arguments is NaN, then a NaN is returned using the usual NaN propagation rules. For this operation, -0.0 is considered to be strictly less than +0.0.
Note that, unlike most intrinsics, this is safe to call;
it does not require an unsafe block.
Therefore, implementations must not require the user to uphold
any safety invariants.
