quick question

[sunit_modi]

if i want to display a float variable to 2 decimall places, who do i do it

problem is that i am displaying a monitory value but if it is only 1 decimal place is just shows the 1 decimal place from a variable called total, ie

£31.9

which should be £31.90

please help, had a look at the manual quickly but to no avail.

Many Thanks

Sunit

I can't remember offhand the exact syntax, but the function to look up is number_format

try
number_format($num, 2);

[bernouli]

use the pringf() function

$money= 31.9 ;
printf("£= %.2f",$money);

You could try:

$newtotal=round($total, 2);

[bernouli]

All that jshea wants is no round() function,
he would only type the number in 2 decimal after comma

You were right. It is early and I misinterperited the question.

Thanks for clarifying.
