I need to compare to double variables like this if (distance <= radius) both distance and radius are doubles and I remember in class how to use epsilon comparisons for checking equality but how would I do it for <= or >?

If we have double numbers, let's say I want to see if some double parameter is equal to zero that is passed as double: public bool AlmostEqual(double x, double y) { double epsilon = Math.Max(Math.Abs(x), Math.Abs(y)) * 1E-15; return Math.Abs(x - y) <= epsilon; } considering double show...

On telephoto (and retrofocus, and zoom) lens design: The simple definition of a telephoto lens is a lens that has a focal length longer than the physical lens. Many lenses that are 'long' (as opposed to 'normal' or 'wide') are telephoto in design. This is because it sometimes is impractical to...

This ought to achieve what you're looking for. (ie. how to tell that something was written to stdout) #include <sys/stat.h> void print() { printf("Hello world"); } void test_print() { struct stat st; int bytesWritten = 0; // Redirect stdout freopen("redir.txt", "w", stdout...

There are several ways to approach this, and there are two 'problems' that you are looking at. The first is the panoramic format... One could use the approach done by photographers who shot APS-P images (or put a mask over a 5x7" (127mm x 177mm) slide or negative to get a a 60mm x 170mm frame (...
