I have a question regarding number formating in PHP. I have a variable called "average", which is simply an average of a few values. To make it clear I rounded the number to 2 decimal places. Now the problem is, that if the average is for example 2.90, it only shows 2.9. Is there any way of displaying 2 decimal places always? I though I could do it by multiplying the number by 100, rounding it to zero d.p. and then divide by 100 again, but that seems a bit overcomplicated if there is an easier way of doing it.

    How are you rounding the number? You could just use number_format($number, 2, '.', ''); You could also use sprintf('%0.2f', $number); – joe42 Oct 08 '13 at 22:01

Maybe you can try the number_format(float $number [, int $decimals = 0 ])?

For more information, take a look at http://php.net/manual/en/function.number-format.php

Format the output with printf 

printf("%.1f", $num); // prints 1 decimal place
printf("%.2f", $num); // prints 2 decimal places
