Random Rounding Error??

[AnthonyGalante]

I have a field that is double with no defined precision or scale and populated with real numbers.
I create a new field, same format, and use field calc to subtract each number by .01
I create another field, same format, use field calc to subtract new number from original.
I get results, seemingly randomly, that range from .01 to .009xx.
WHY?
