Is there an exponent operator in Swift?

THere's no functions dedicated for payment, interest, and principal in the Swift Standard Library.

If your exponent operator means `^` in VB or Excel (or `**` in Fortran), you can use the `pow` function.

`pow(a, b)` is the equivalent to `a^b` in VB or Excel.

The `pow` function works on (Decimal, Int) in addition to (Double, Double). If you are planning to write an app including finaicial calculation,

you need to clarify how much calculation error would be accepted and if it it appropriate to use the `pow` function.

Thank you very much. I figured it out. My application calculates correctly but how do I convert the string to U.S. currency? I just took programming in Visual Basic but I want to write iPhone apps. I have watched a lot of hours in tutorials and I am still learing.

Thank you.
