Integer to Float

[Anon]

Hi. How can i convert an integer to a float number with a precision of 2. For example i want to convert 12 to 12.00 .

Do i have to float the integer $num first and then round it with
round($num, 2) ???

I haven't found any help on this in the manual.

Thanks.

Hmm, you can use an integer in a float operation without any modification.

BUT: if you mean "how can I print 12.00 instead of 12", then use the number_format function

$number = 12;

print "The number is: " . number_format($number, 2);

there are more usages for number_format (you can put in commas, delimiters, etc). Check out it's manual entry:
