On Linux, feenableexcept and fedisableexcept can be used to control the generation of SIGFPE interrupts on floating point exceptions. How can I do this on Mac OS X Intel? Inline assembly for enabling floating point interrupts is provided in http://developer.apple.com/documentation/Performance/Conceptual/Mac_OSX_Numerics/Mac_OSX_Numeric...
I'd like to play with those traps for educational purpose. A common problem with the default behavior in numerical calculus is that we "miss" the Nan (or +-inf) that appeared in a wrong operation. Default behavior is propagation through the computation, but some operation (like comparisons) break the chain and loose the Nan, and the res...
I have an issue that I can't seem to solve. I am randomly generating numbers in order to determine if my numbers are relativity prime. Here is the function that gives me a Floating Point Exception: bool modularExponentiationTest(unsigned long long exponent, unsigned long long modulus) { short index = 0; unsigned long long base;...
