Hi,

Is there any fonctions for the twin complement ?

For example with 10 (in hexa) the twin complement is 16 but when I tried to
get it in my computer with
(~value)+1
... it's completly wrong because the programme do the "non" booleen
operation on all the bits

I will have to make it myself or there is a fonction for it ?

thank you for your help,

Florent.
