Android Question Animated Counter with negative Values

Hello,

I'm trying to use that class :
https://www.b4x.com/android/forum/threads/b4x-xui-animated-counter.90505/

do you think it would be possible to modify that kind of animated counter class with negative values range ,
for example like : from -100 to +100 ?
or should i create a completely new class for a such need ?

regards
Michel
