# Function core::intrinsics::rintf32

    pub unsafe extern "rust-intrinsic" fn rintf32(x: f32) -> f32

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

Returns the nearest integer to an `f32`. Changing the rounding mode is not possible in Rust, so this rounds half-way cases to the number with an even least significant digit.

May raise an inexact floating-point exception if the argument is not an integer.

The stabilized version of this intrinsic is `f32::round_ties_even`
