# Function maximumf64

    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.
