<p>The Precision Floating-Point Exception is signaled according to the immediate operand. If any source operand is an SNaN then it will be converted to a QNaN. If DAZ is set to ‘1 then denormals will be converted to zero before rounding.</p>
<p>The sign of the result of this instruction is preserved, including the sign of zero.</p>
<p>The formula of the operation for VRNDSCALESS is</p>
<p>ROUND(x) = 2<sup>-M</sup>*Round_to_INT(x*2<sup>M</sup>, round_ctrl),</p>
<p>round_ctrl = imm[3:0];</p>
<p>M=imm[7:4];<
