<h1>Sar repetitions</h1>
<h1>Parameters</h1>
<table>
<tr>
<td>
repetitions = number of shifts to make right
</td>
</tr>
</table>
<h1>Description</h1>
<table>
<tr>
<td>
This performs a right binary shift on the value the specified number of times.  This basically is a faster method of dividing the value exponentially. By shifting  right once, you are dividing the value by 2. By shifting right twice, you divide  by 4, etc.

<br />

<br />
Sar command varies from Shr whereas it fills blank bits  shifted with copies of the sign bit, 0 for positive numbers and 1 for negative. 

<br />
The usefulness of this command is basically faster math execution. Also see Shl.
