# Function std::intrinsics::powif64[−][src]

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

The stabilized version of this intrinsic is `f64::powi`
