I am using DMC version 8.38 on Win32. The result of comparing two doubles seems to get wrong sometimes when a long double and the ?: operator are involved. Maybe I am wrong, but I think the following code should return 0, not 1. Thanks in advance for any suggestions. Robert #include <stdio.h> #include <math.h> int main(void) { double x, y; long double z; x = sqrt(1); y = sqrt(2); z = 0; printf("y > x, so the return value should be zero (false). It isn't."); return y < (1? x : z); }
