Note Submitter: dev@maintainfit.com ---- I was trying to find the negative value of a formatted float, but going about it the wrong way. The following script illustrates what I was doing wrong, <? $float_value = -1231.3448852; //note that this float will have a comma added by number_format echo $float_value." \n"; echo number_format($float_value,2)." \n"; //this is fine echo -number_format($float_value,2)." \n"; //here's the error echo number_format(-$float_value,2)." \n"; //this is fine /* output: -1231.3448852 -1,231.34 1 1,231.34 */ $float_value = -131.3448852; //note that this float will NOT have a comma added by number_format echo $float_value." \n"; echo number_format($float_value,2)." \n"; //this is fine echo -number_format($float_value,2)." \n"; //this works because number_format does not place a comma in the returned number echo number_format(-$float_value,2)." \n"; //this is fine /* output: -131.3448852 -131.34 131.34 131.34 */ ?>
