Function std::intrinsics::rintf64

pub unsafe extern "rust-intrinsic" fn rintf64(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

Returns the nearest integer to an f64. May raise an inexact floating-point exception if the argument is not an integer.
