Two decimal places

[Anon]

How do I calculate a number so that it only shows two decimal places?

Like 5/12= 0.42 instead of 0.4166666667

from the user contributed example:

$new_number = number_format($my_float,2);

The round() function is the traditional way to do that.

both number_format() and round() will round the number, however round() will leave off the trailing zeros which can be important. the orginal poster didn't say he needed to round the number, just show two decimal places. but its likely both functions will work for what he is trying to do.

$a = "4.4";
$b = "4.5";

echo "number_format(a): ", number_format($a,2), "\n"; #output is 4.40
echo "number_format(b): ", number_format($b,2), "\n"; #output is 4.50

echo "round(a): ", round($a,2), "\n"; #output is 4.4
echo "round(b): ", round($b,2), "\n"; #output is 4.4
