# [−][src]Function std::intrinsics::copysignf32

    pub unsafe extern "rust-intrinsic" fn copysignf32(x: f32, y: f32) -> f32

🔬 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

Copies the sign from `y` to `x` for `f32` values.

The stabilized version of this intrinsic is `std::f32::copysign`
