    Post Make a Positive Number - Negative

    How do i make a positive number which is assigned to a variable, a negative one.

    So

    PA = (Aptelev) - (intDiffQ)

    If intDiffQ was positive, how do i make it negative before storing it in PA. Is there a Function to it?

    the reason I ask is because sometimes the value of Aptelev is -12 and the value of intDiffQ is Positive. I want the answer to be positive but i keep getting a negative number!


    Any ideas?

    if number > 0 then number = number * -1

    well, math is a lot like that. If you subtract a negative number from a negative number, you'll get a negative number.

    sounds like what you want is the absolute value. see "abs" function

    Hmm, you know actually that isn't true:

    (-4) - (-8) = +4

    But I'm sure you knew that...

    you can make a number negative just by multiplying it with -1 or just puttiing - sign before the variable..

    that will only work if the number = positive

    -(-5) = 5
    -(5) = -5
    a = -5
    -a = 5

    If you can't do simple addition/subtraction, maybe you should choose a new career track...

    if i understand you right you want this

    intDiffQ = intDiffQ - (intDiffQ * 2)
    We don't know what's wrong. . . So the best bet might be to remove something surgically.

    If intNumber is a variable that contains either a negative or positive value then:

    VB Code:
    1. intNegativeNumber = - Abs(intNumber)

    intNegativeNumber will always contain the negative value.
