# [−][src]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.
