## sqrtss, sqrtsd, sqrtps, sqrtpd - square root

    dest = sqrt(source)

The sqrtss, sqrtsd, sqrtps, and sqrtpd instructions computer the square root of the source value (second operand) and store the result(s) in the destination operand. There are also vsqrtss, vsqrtsd, vsqrtps, and vsqrtpd on CPUs with AVX instructions which can compute multiple values at once. Behaviorally these instructions are similar to the various add instructions should you wish to see more details.

            sqrtss   xmm0, xmm1          ; xmm0 gets 32 bit sqrt of xmm1
            sqrtsd   xmm0, [x]           ; xmm0 gets 64 bit sqrt of x
            sqrtps   xmm0, [rdi]         ; xmm0 gets 4 32 bit sqrts of [rdi]
            sqrtpd   xmm0, [x+4*rcx]     ; xmm0 gets 2 64 bit sqrts of array x
            vsqrtps  ymm3, ymm15         ; ymm3 gets 8 32 bit sqrts of ymm15
            vsqrtpd  ymm3, [x]           ; ymm3 gets 4 64 bit sqrts of array x
