Square Root Scalar Single-Precision<br />

Floating-Point<br />

Computes the square root of the low-order single-precision floating-point value in an<br />

XMM register or 32-bit memory location and writes the result in the low-order<br />

doubleword of another XMM register. The three high-order doublewords of the<br />

destination XMM register are not modified. Taking the square root of +infinity<br />

returns +infinity.<br />
