# 1.27.0[−][src]Function core::arch::x86_64::_mm_cmpunord_ss

    pub unsafe fn _mm_cmpunord_ss(a: __m128, b: __m128) -> __m128

This is supported on x86-64 and target feature `sse` only.

Checks if the lowest `f32` of both inputs are unordered. The lowest 32 bits of the result will be `0xffffffff` if any of `a.extract(0)` or `b.extract(0)` is a NaN, or `0` otherwise. The upper 96 bits of the result are the upper 96 bits of `a`.
