Need help with this floating number

Hi there…

Okay just a quick shoot … how to round this operation so the result will be
**7.20

**and this what I have so far…



stop();

var basicsalary:Number;

basicsalary = 1502.09;
theresult = basicsalary*0.00479233226837061

trace(theresult);//output = 7.19851437699681

//should be 7.20 round the 2 digit after the floating point...



Really need help withthis…sorry for being such novice…

thanks in advanced
