RCPSS
Usage: RCPSS dest,src Modifies flags: None
Computes an approximate reciprocal of the low single-precision floating-point value in the 'src' and stores the single-precision floating-point result in the 'dest' operand.
Scalar Single-Precision FP Reciprocal
RCPSS xmm1,xmm2/m128 ; F3 0F 53 /r [KATMAI,SSE]
RCPSS returns an approximation of the reciprocal of the lower single-precision FP value from xmm2/m32; the upper three fields are passed through from xmm1. The maximum error for this approximation is: |Error| <= 1.5 x 2^-12.
The 'src' operand can be an XMM register or a 32-bit memory location. The 'dest' operand is an XMM register. The three high-order doublewords of the 'dest' operand remain unchanged.
