Decimal place

[Alv]

How do I return a value with only three decimal place? Currently my calculated form value have this value 76437.13500000001. How can I round the value to three decimal place and return them so that user sees 76437.135.

Thanks in advance.

Try this:

num = parseInt(document.formname.inputname.value);
num = Math.round(test*1000)/1000;

In addition to what adam suggested for browsers supporting javascript 1.5 (all generation 6 + browsers)
you should be able to use a simpler solution
if you have number
var num = 76437.13500000001;

alert(num.toFixed(3))

will return

76437.135

Khalid, the reason I posted that way is because it is more supported(as you said). Also, with my method, it rounds rather than just cutting it at the third digit. Just wanted to point out the differences so that Alv would know... ;)

sorry if seemed that way,I did not mean to undermine your response in anyway,just wanted the thread owner to know that he has another option too in newer browsers..:-)

Also, with my method, it rounds rather than just cutting it at the third digittoFixed will round to the specified number of digits.
