Function core::arch::x86_64::_mm_maskz_roundscale_sd   [−][src]
pub unsafe fn _mm_maskz_roundscale_sd<const IMM8: i32>(
    k: __mmask8, 
    a: __m128d, 
    b: __m128d
) -> __m128dThis is supported on x86-64 and target feature 
avx512f only.Expand description
Round the lower double-precision (64-bit) floating-point element in b to the number of fraction bits specified by imm8, store the result in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper element from a to the upper element of dst.
Rounding is done according to the imm8[2:0] parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT // round to nearest
_MM_FROUND_TO_NEG_INF     // round down
_MM_FROUND_TO_POS_INF     // round up
_MM_FROUND_TO_ZERO        // truncate
_MM_FROUND_CUR_DIRECTION  // use MXCSR.RC; see _MM_SET_ROUNDING_MODE
