# Function core::intrinsics::nearbyintf64

    pub unsafe extern "rust-intrinsic" fn nearbyintf64(x: f64) -> f64

🔬This is a nightly-only experimental API. (`core_intrinsics`)
Expand description

Returns the nearest integer to an `f64`. Changing the rounding mode is not possible in Rust, so this rounds half-way cases to the number with an even least significant digit.

This intrinsic does not have a stable counterpart.
