I have defined a variable as being a variable parameter with a range of 0 to 10 and having units of int. If I set the initial value (in the box below) to 0, when I save the equation and go back in, I see that the units have been changed to real. If I keep everything the same, but set the initial value to 1, the units stay as int. What gives? (using 6.4 on a Mac)
