Format float

[WJ Zeeuwen]

Hi all,

Is it possible to adjust the number of digits in a float?

For example $test = 1/3; echo ($test); gives 0.33333333.. But i only
want 0.33
Is there a function or do i have to use round($test*100 )/100

Thanx,
WJ

I'd use round($test,2);
Also possible is number_format() ;

If all you want to do is display the value 0.33 without actually changing the
number (which will affect future math operations), you can use

printf("%01.2f" , 0.33);
