----
the function in the note below seems a bit more complicated then it really needs to be. since we
are dealing with strings, we can use the string functions instead.
<?php
function DecimalClean($Input)
{
return (strpos($Input, '.') === false) ? $Input : rtrim($Input, '0');
}
?>
Explanation:
First we check to see if the number contains a decimal point (we assume that it is a sane/valid
number).
If the number lacks a decimal point then we do not need to do anything, otherwise we use the trim
function which is very fast because it is a low level function, to remove the zeros. Trim will stop
at the first character that is not a '0'.
The only limitation is that this version does not account for localized decimal points.
