# SQRTPS
# Compute Square Roots of Packed Single-Precision Floating-Point Values
| Opcode | Mnemonic | Description |
|---|---|---|
| 0F 51 /r | SQRTPS xmm1, xmm2/m128 | Compute the square root of the packed single-precision floating-point values in xmm2/m128 and store the results in xmm1. |
# Description
Performs an SIMD computation of the square roots of the four packed single-precision floatingpoint values in the source operand (second operand) stores the packed single-precision floatingpoint results in the destination operand. The source operand can be an XMM register or a 128- bit memory location. The destination operand is an XMM register. See Figure 10-5 in the IA-32 Intel Architecture Software Developer's Manual, Volume 1 for an illustration of an SIMD single-precision floating-point operation.
# Operation
Destination[0..31] = SquareRoot(Source[0..31]);
Destination[32..63] = SquareRoot(Source[32..63]);
Destination[64..95] = SquareRoot(Source[64..95]);
Destination[96..127] = SquareRoot(Source[96..127]);
