Function core::intrinsics::powif64

pub unsafe extern "rust-intrinsic" fn powif64(a: f64, x: i32) -> 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

Raises an f64 to an integer power.
