Well, that is always possible. > Computer floats are not real numbers: they are discrete elements of > a finite set. Yes, I now that. Ok, I thought you meant floats in the cited paragraph. > Their behavior is more difficult to comprehend than the behavior of > integers. It seems some people are "scared" by floats, is it that you mean? And --- integers have their trouble spots also, consider: A, Is -1/2 equal to -1 or -0 Is -1%2 equal to -1 or +1 B, Why does #include <stdio.h> int main(void) { char cc = 0xc4 // 'ä' in latin1 short str = cc; printf("0x%04hx\n", str); } print 0xffc4 instead of 0x00c4 ? But the comprehension dimension of numbers is not for me to discuss, but if someone has problems with it, I'm willing to help out.
