VGETMANTSS



Extracts the mantissa from a scalar single-precision floating-point value.

The following table covers what the source and destinations can be.

source destination(s)
xmm xmm
m4 xmm

DO NOT support LOCK

This instruction is only available when the processor is operating in 64-bit mode or compatibility mode and requires the AVX instruction set to be enabled.

The destination register is overwritten with the extracted mantissa; previous values in the register are lost. If the source operand is a signaling NaN, a #I exception SHALL be generated. For quiet NaNs, the mantissa is extracted without triggering an exception. The result is stored in the destination as a single-precision floating-point value where the mantissa represents the fractional part of the original number.
