Solution : MOD function ax 2012/ ax 2009 for real Values.

If we need a mod function that we can pass a real values... we can write our own method like this:

Navigation Path:
AOT > Classes >  Global > Create a new Method:

real RealMod(real a, real b) 

{
    ; 

    return (a - ((trunc(a / b) * b))); 

}

Hope this helps all you guys there. :)

Happy Daxing.
