Function core::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

This is supported on non-crate feature miri-test-libstd or test or doctest only.

Returns the smallest integer greater than or equal to an f64.

The stabilized version of this intrinsic is f64::ceil
