core::intrinsics::copysignf32

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

Unstable (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

Copies the sign from y to x for f32 values.
