note 7327 deleted from Floating point numbers by jmcastagnetto

Dear all,<br> I try to add two double number (which from mysql) and want to display the decmial point even it is zero, like that:<br> $pt1 = doubleval($col1);<br> $pt2 = doubleval($col2);<br> $pt3 = $pt1+$pt2; <br> /*display xx.xx when $pt1=aa.aa or $pt2=aa.aa*/<br> /* when $pt1=aa and $pt2=bb, $pt3=xx rather than xx.00 */<br> Is that had any easy way to add zero's to the end? (although can use strlen to check the length and add zero, but seem must had a good method). <br> Thx a lot.
