Function std::intrinsics::ceilf64

pub unsafe extern "rust-intrinsic" fn ceilf64(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 smallest integer greater than or equal to an f64.

The stabilized version of this intrinsic is f64::ceil
