Function to reverse integer?

[Disyne]

Hi

Is there a function to reverse an integer?

For example ReverseInt(24) would return -24 or ReverseInt(-10) would return 10.

Thanks.

See if this helps,

Private Function ReverseInt(Value As Integer) As Integer

    If Value < 0 Then
        ReverseInt = Abs(Value)
    Else
        ReverseInt = -Value
    End If

End Function

I've never heard of that as the 'reverse' of a number, the 'negative' is the usual way to describe it.

The way to do it is to simply use a - sign, eg:

MyVariable = 24  'set initial value

MyVariable = -MyVariable  '"reverse" it

edit: hmm.. it seems I was quite slow, but at least I provided a different (and in this case simpler) solution!

I've always used the ABS() command hehe, so what's it good for then?

[si_the_geek]

The Abs function returns the absolute (always positive) version of the number, whether it was already positive or not (so -10 and 10 would both give 10).

When/how that would be useful depends on what you are doing.. just like getting the negative of a number (as we did here) is.

whether it was already positive or not

Oh ya thats right, I need more coffee.

Si's solution is obviously the best, but this appeals to my warped mind (only applies to whole numbers)

intI = Not intI -1
