If no decimals, add default ones

Question

Having the following decimal numbers:

• 47.44
• 180.11
• 340
• 12.39
• 25

I was wondering, how can I add a default .00 to those numbers, that have no decimals?

Answer 1

You can use number_format() like that:

number_format($number, 2);

It'll always return number with two decimals. Also it'll separate thousands with ',' (if you don't want that, add '' as fourth parameter).
