Function std::intrinsics::fsub_fast

pub unsafe extern "rust-intrinsic" fn fsub_fast<T>(a: T, b: T) -> T where
    T: Copy, 

🔬 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

浮点减法允许基于代数规则进行优化。 可以假设输入是有限的。

此内联函数没有稳定的对应对象。
