Hello,
how can I change the sign of an Integer Value like

Abs?(100)
-> -100

Thanks,
Andreas

multiple by -1 will always toggle the sign...

-1 * 40 = -40
-1 * -40 = 40

abs() will always make something positive

abs(40) = 40
abs(-40) = 40

abs() * -1 will always make it negative

abs(40) * -1 = -40
abs(-40) * -1 = 40

(abs is defined in system.math)

Multiply it by -1.
