Function core::intrinsics::copysignf64[][src]

pub unsafe extern "rust-intrinsic" fn copysignf64(x: f64, y: 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

Expand description

Copies the sign from y to x for f64 values.

The stabilized version of this intrinsic is f64::copysign
