Question

Just a little bit stuck, trying to find the right function to use:

$number = "4.999";
echo number_format($number, 2); //5.00

We want it to display as 4.99 – what PHP function should we use which won’t round anything, just purely limit the numbers after the decimal point to two?

Answer 1

use printf:

printf('%.2f', $number);

(%.2f prints float numbers with 2 decimal places)

edit I’ve read your question wrong the first time. What you are asking for is rounding down the number to 2 decimal places, then display it:

$number = floor($number*100)/100;
printf('%.2f', $number);
