floating point in javascript

[kundan varma]

Hi All
I have a function below which gives 5 with 0.05*100 but with 0.07, it gives 7.000000000000001 . Why and how to solve it?
function calc()
{
var a=0.05;

var b=0.07;





alert(a*100)

alert(b*100)
}

Thanks
kundan

read this and you will understand the problem with the math: http://www.bugnet.com/alerts/bugalert9298.html

To fix it you can always round you answers to the 10th+ place. Not the best solution! Or you can loo at toFixed()
