# [−][src]Function core::intrinsics::maxnumf64

    pub unsafe extern "rust-intrinsic" fn maxnumf64(x: f64, y: f64) -> f64

🔬 This is a nightly-only experimental API. (`core_intrinsics`)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Returns the maximum of two `f64` values.

The stabilized version of this intrinsic is `std::f64::max`
