If I declare the types of the vars as Double, then I get a rounding error. If I choose extended (much greater accuracy than the processor manages by itself), I get 0. So, from this, it would appear that Delphi is defaulting its types to something that bypasses the hardware and uses its own libraries to calculate. If I use a type that maps to a hardware type then the error is there... I agree that this is a hardware issue. Even if I multiply the result by a very large number, with Extended, Comp and Currency I still get 0. With single, double, and real48 I get rounding issues. Delphi 7 types.
