MM register destination are copied from corresponding bits in the first source operand.</p>
<p>The destination must be a XMM register, the source operand can be a XMM register or a float32 memory location. The the low doubleword element of the destination operand is conditionally updated with writemask k1.</p>
<p>Each GETEXP operation converts the exponent value into a FP number (permitting input value in denormal representation). Special cases of input values are listed in <a href="./VGETEXPPS.html#tbl-5-1
