Function std::intrinsics::roundf64

pub unsafe extern "rust-intrinsic" fn roundf64(x: 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

Returns the nearest integer to an f64. Rounds half-way cases away from zero.

The stabilized version of this intrinsic is f64::round
