# 1.27.0[−][src]Function core::arch::x86::_mm_floor_sd

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

This is supported on x86 and target feature `sse4.1` only.

Round the lower double-precision (64-bit) floating-point element in `b` down to an integer value, store the result as a double-precision floating-point element in the lower element of the intrinsic result, and copies the upper element from `a` to the upper element of the intrinsic result.
