[RESOLVED] calculation -floating point

[nectarapricot]

Hi all.
I did some calculation and the result appears like this
17.2962962963%

how should I change it to 2 floating point= 17.30%

the variable for the result value come from
.($Totalrank[$temp_i]/$total_weight)*100

to make it easier i assigned it to another value
$weight.

where and how should I change so that I get the value as mentioned above?
many thanks
