jCalc is a very simple calculator but it still has some advantages over the built in calculator from Microsoft.
It is more colorful, that is if you are using a color PDA, and it does the calculations correctely.
The problem with the built in calculator is that 3*4+4*3 = 48 when it should be 24.
That is because Microsoft didn't think of a thing called precedence, i.e. you should do all the multiplications and divisions first.
jCalc will do this correctely.
