'''command''' neg ''operand''

The neg instruction will subtract the operand from itself twice.

Example:
<pre>1 - 1 = 0

0 - 1 = -1</pre>

This is what neg instruction perform.

<pre>Operand = -Operand</pre>

<div style="padding:2px;border:1px dashed #2f6fab;background-color:#f4f4f4;">
Replaces the value of operand (the destination operand) with its two's complement. (This operation is equivalent to subtracting the operand from 0.) The destination operand is located in a general-purpose register or a memory location.
