    As to math and floating numbers there are results to consider when using absint(). Here are some tests.

    echo '<ul>
<li>0      returns '. absint( 0 ) . '</li>  
<li>1      returns '. absint( 1 ) . '</li>
<li>-1     returns '. absint( -1 ) . '</li>
<li>-1 + 1 returns '. absint( (-1 + 1) ) . '</li>
<li>1 * -1 returns '. absint( (1 * -1) ) . '</li>
<li>1 / -1 returns '. absint( (1 / -1) ) . '</li>
<li>1 - 1  returns '. absint( (1 - 1) ) . '</li>
<li>0 * -1 returns '. absint( (0 * -1) ) . '</li>
<li>0 / 1  returns '. absint( (0 / 1) ) . '</li>
<li>0 - 1  returns '. absint( (0 - 1) ) . '</li>
<li>0.99 * 1  returns '. absint( (0.99 * 1) ) . '</li>
<li>1.99 * 1  returns '. absint( (1.99 * 1) ) . '</li>
<li>0.99 / 1  returns '. absint( (0.99 / 1) ) . '</li>
<li>1.99 / 1  returns '. absint( (1.99 / 1) ) . '</li>
</ul>';
