Has anyone had any problems substracting floats? I have the following code: (C166 V4.23 compiler) float dummy, test1, test2; test1 = 1.0e10; test2 = 1.1e10; dummy = test2 - test1; for some reason dummy comes out as 1.000001e9 I've tried declaring them as doubles and get the same result. DS
1.000001e9 is close enough to 1.0e9, isn't it? If it's not for you, move to double. If FLOAT64 directive is not specified, THE C166 COMPILER uses single-precision floating-point arithmetic even if the double keyword is used in the C source file. Go to C166 in the target settings and check the Double-precision Floating Point option. - Mike
