Function std::intrinsics::powf64

pub unsafe extern "rust-intrinsic" fn powf64(a: f64, x: 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

Raises an f64 to an f64 power.

The stabilized version of this intrinsic is f64::powf
