number_format
stupidly rounds numbers by default. Is there just a simple way to turn off the rounding? I'm working with randomly generated numbers, and I could get things like...
42533 * .003 = 127.599 or,
42533 * .03 = 1275.99 or,
42533 * .3 = 12759.9
I need number_format (or something else) to express the result in traditional US format (with a comma separating the thousands) and not round the decimal.
Any ideas?
The second argument of number_format is the number of decimals in the number. The easiest way to find that out is probably to treat it as a string (as per this question ). Traditional US format is default behaviour, so you don't need to specify remaining arguments.
$num_decimals = strlen(substr(strrchr($number, "."), 1));
$formatted_number = number_format($number, $num_decimals);
If anyone's interested in this, I've written a little function to get around this problem.
With credit to Joel Hinz above, I came up with...
function number_format_with_decimals($value, $round_to){
//$value is the decimal number you want to show with number_format.
//$round_to is the deicimal place value you want to round to.
$round_to_decimals = strlen(substr(strrchr($value, "."), $round_to));
$ans = number_format($value, $round_to);
return $ans;
}
I tried these solutions, but what ended up being my answer was this:
$output=money_format('%!i', $value);
This gives you something like 3,234.90 instead of 3,234 or 3,234.9
