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

    pub unsafe fn _mm_cvtss_sd(a: __m128d, b: __m128) -> __m128d

This is supported on x86-64 and target feature `sse2` only.

Converts the lower single-precision (32-bit) floating-point element in `b` to a double-precision (64-bit) floating-point element, store the result in the lower element of the return value, and copies the upper element from `a` to the upper element the return value.
