Formula computation always returns ZERO

[SammyC]

Hi

Been really scratching my head on this one
I have a very simple formula
all of the values are none ZERO ( see the attached screenshot of the OUTOUT Window)
but my computed value is always ZERO.
I even multiplied by 10000 instead of 100 and i get the same results

I would be truly grateful if someone could tell me why...
is it a c# variable issue?
is it a problem with the INT and DOUBLE?

Thank you kindly in advance

Sammy

//variables

private double Average1=0;
private int a=0, b=0;


protected override void OnBarUpdate()

.....

Average1 = ((a-b)/(a+b))*100;

Print("average1 = "+Average1);
Print("a= "+a);
Print("b= "+b);
Print("(a-b)= "+(a-b));
Print("(a+b)= "+(a+b));

Sammy, this is indeed a precision issue you run into, try for example this -

Average1 = ((double)a - (double)b)/((double)a + (double)b);

Thank you Bertrand...
the double in front fixed the problem

Maybe this would have worked as an alternative:

private double Average1=0;
private double a=0, b=0;
