Function std::intrinsics::maxnumf64

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

🔬 This is a nightly-only experimental API. (core_intrinsics #0)

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.
