VGETMANTPS—Extract Float32 Vector of Normalized Mantissas from Float32 VectorInstruction Operand EncodingDescriptionConvert single-precision floating values in the source operand (the second operand) to SP FP values with the mantissa normalization and sign control specified by the imm8 byte, see Figure5-15. The converted results are written to the destination operand (the first operand) using writemask k1. The normalized mantissa is specified by interv (imm8[1:0]) and the sign control (sc) is specified by bits 3:2 of the immediate byte. The destination operand is a ZMM/YMM/XMM register updated under the writemask. The source operand can be a ZMM/YMM/XMM register, a 512/256/128-bit memory location, or a 512/256/128-bit vector broadcasted from a 32-bit memory location.For each input SP FP value x, The conversion operation is:GetMant(x) = ±2k|x.significand|where:1 <= |x.significand| < 2Unbiased exponent k can be either 0 or -1, depending on the interval range defined by interv, the range of the significand and whether the exponent of the source is even or odd. The sign of the final result is determined by sc and the source sign. The encoded value of imm8[1:0] and sign control are shown in Figure5-15.Each converted SP FP result is encoded according to the sign control, the unbiased exponent k (adding bias) and a mantissa normalized to the range specified by interv.The GetMant() function follows Table 5-7 when dealing with floating-point special numbers.This instruction is writemasked, so only those elements with the corresponding bit set in vector mask register k1 are computed and stored into the destination. Elements in zmm1 with the corresponding bit clear in k1 retain their previous values.Note: EVEX.vvvv is reserved and must be 1111b, VEX.L must be 0; otherwise instructions will #UD.Opcode/InstructionOp/En64/32 bit Mode SupportCPUID Feature FlagDescriptionEVEX.128.66.0F3A.W0 26 /r ibVGETMANTPS xmm1 {k1}{z}, xmm2/m128/m32bcst, imm8AV/VAVX512VLAVX512FGet normalized mantissa from float32 vector xmm2/m128/m32bcst and store the result in xmm1, using imm8 for sign control and mantissa interval normalization, under writemask.EVEX.256.66.0F3A.W0 26 /r ibVGETMANTPS ymm1 {k1}{z}, ymm2/m256/m32bcst, imm8AV/VAVX512VLAVX512FGet normalized mantissa from float32 vector ymm2/m256/m32bcst and store the result in ymm1, using imm8 for sign control and mantissa interval normalization, under writemask.EVEX.512.66.0F3A.W0 26 /r ibVGETMANTPS zmm1 {k1}{z}, zmm2/m512/m32bcst{sae}, imm8AV/VAVX512FGet normalized mantissa from float32 vector zmm2/m512/m32bcst and store the result in zmm1, using imm8 for sign control and mantissa interval normalization, under writemask.Op/EnTuple TypeOperand 1Operand 2Operand 3Operand 4AFullModRM:reg (w)ModRM:r/m (r)Imm8NA
