How to allow a number with two decimal places in javascript?

Hello Friends, If you want to display any number with two decimal digits then you need to use toFixed() JavaScript function during parsing the float number.

Example : I want to display cart total amount with two decimal places only. Let say actual total amount is 123.4567 and I want to display amount is 123.45 only

var value = 123.4567;
var twoPlacedFloat = parseFloat(value).toFixed(2);
alert(twoPlacedFloat);

If you want to display number with more the two digits then you can change value under toFixed() function. Let say if want to display number up to 4 digits then pass 4 value in toFixed function, i.e toFixed(4)

Enjoy!
