Math functions

[rkeppert]

I received this code to help me out with math function on a page...

Problem is, when it puts the value into the tfees box, it comes out like 232.5 instead of 232.50

Can anyone tell me how to fix this?

function  doMath() {
var one = eval(document.warr.costs.value)
var two = eval(document.warr.cfee.value)
var three = eval(document.warr.wfee.value)
var prod = one + two + three
document.warr.tfees.value=custRound(prod,2);
}
function custRound(x,places) {
return (Math.round(x*Math.pow(10,places)))/Math.pow(10,places)
}

thanks

assuming tfrees box is some kind of display you should use sprintf or printf functions

another choice is number_format

I typically use number_format

tfees box is a text input box marked readonly... the value is placed in the box but can't be manually changed without a change being made to one of the other 3 fields.
