Function core::intrinsics::roundf32

pub unsafe extern "rust-intrinsic" fn roundf32(x: f32) -> f32

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

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

返回最接近 f32 的整数。将中途案例从零舍入。

此内联函数的稳定版本是 f32::round
