VSQRTSH



Computes the square root of a packed signed short floating-point value.

The following table covers what the source and destinations can be.

source destination(s)
m16 r128
r128 r128

DO NOT support LOCK

This instruction is available only when using the AVX extension. It operates on packed 16-bit floating-point values (half-precision).

If the source operand contains a negative value, the result is a NaN (Not-a-Number) and the #I exception is signaled. If the source is zero, the result is zero and no exception is signaled. If the source is a NaN, the result is a NaN.

Precision control: The instruction is subject to the rounding control bits in the MXCSR register. If the result is not exact, the #P exception is signaled.
