Is it possible in project settings to set vb.net in such a way so that it
considers only upto 3 decimal places when comparing any two values.

My problem is:

i get varA = -0.0000000000018189894035458565. It actaully should be zero.
So when i compare varA = 0 , it returns false (obviously)
I can use round(varA) to achieve what i want, but i have to do that every
time. Is it possible to set it in project settings.

No. You can't change the way basic mathematical operators work. Especially
on a per project setting, since in the end, the IL is interpreted by the
CLR, who doesn't know or care what project your assembly was compiled in. It
treates all floating point numbers the same way, it's not going to treat
them differently depending on what assembly the code is executing in.

I would suggest you write a function to do the comparison, that will then do
the rounding appropriately. That way comparing 2 numbers is still one call
and you don't have messy rounding code all over the place.
