Function std::intrinsics::fmaf32

pub unsafe extern "rust-intrinsic" fn fmaf32(a: f32, b: f32, c: 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

为 f32 值返回 a * b + c。
