Function std::intrinsics::ceilf64

pub unsafe extern "rust-intrinsic" fn ceilf64(x: f64) -> f64

🔬 This is a nightly-only experimental API. (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
