# Help with computations

I'm currently working on an assignment for my Java class, it's supposed to do this:

Write a Java program to read in an integer number (as a String) from the program arguments, and print the value of the following calculation, where n is the number:

if n < 0 - print out (n^2) + (n/2)

if n >= 0 and is even - print out (n^3)*(n-1)

if n >= 0 and is odd - print out (n^-1) + (3n)

The problem is that it doesn't seem to compute the numbers correctly.

When I input -2, it results in 3, which is correct, but when I put in -1, it results in 1, when it should be .5

That seems to be the only part that isn't working and I can't figure out why. Any help is greatly appreciated
