Rounding to two digit in javascript

[jay123]

Hello,
This seems to be very common question, but my problem hasn't been addressed anywhere.

My code look like

var A = Math.round(B * Math.pow(10,2))/Math.pow(10,2);

Now the code works absolutely fine if B is 1.2345.It gets changed to 1.23 (2 digits, hunky dory)

problem starts if B is 1 , I need to display 1.00 instead of 1 as i am assigning this variable A value to some textbox and just for the sake of consistency we need to show every thing upto two decimal places.

I have googled for 2 hours and everyone shows how to round a complex decimal number to 2 decimal points but i haven't come across any webpage showing the solution for my problem.

Any help will be appreciated.

er, B.toFixed(2) or B.toPrecision(2)?

didnt work for my problem Dormilich, ok my whole problem is:

I have a page with a number(A) displayed as label ,Textbox(B) and Button

When one click on button it adds A and B and sum is displayed in textbox(C). Now thats where i want to display data to 2 digit . I tried your toPrecision(2) and in Textbox C it shows 2.3e+3, instead of 2318 (where A(Label) was 2317.28 and i entered in .72 in B)

[Dormilich]

it should work then with .toFixed(2)
