Show dollar and cents in the calculation widget

I added a calculation widget to my form. How do I make it show dollars and cents rather than just a number.

You can add Dollar sign in the calculation and for showing cents, make sure to allow decimal from the advance options. Look at this screenshot:

Thank you!

Where do I add the $ in the equation?

The dollar sign can be placed at any place. For example, you can place it before the actual calculation value.

Thank you.
