Function std::intrinsics::rintf32

source ·
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. However, Rust assumes floating-point exceptions cannot be observed, so this is not something that can actually be used from Rust code.

The stabilized version of this intrinsic is f32::round_ties_even
