Change the +/- on numbers
Hello guys, i am working on solution that has VAT calculations,
So I like to know how to do this :
If you get result for -10 (minus 10) on calculation (any field), i want to convert this value as a 10 (plus 10) and if you get 10 as calculation i want to convert that minus value to plus value it to -10.
How can i convert this : get minus value in to Plus and make it reverce.
* i tried "Abs " function but that convert minus in to plus but not plus in to minus.
Thanks in Advance
