Certainly, the Abs() function is Absolute Value. If the user enters a
negative number (knowing that you're wanting a negative number), such as -2,
then (-2)*(-1) is 2, a positive number. However, the poster wants to always
store a negative value. The absolute value function will always give a
positive number (or zero, of course), so that when you multiply by -1, the
value will be negative.
Abs(-2) is 2
Abs(2) is 2
2*(-1) is -2

Hi Wayne,
could you explain what the 'Abs' is doing?
