I know all numbers stored in variables are stored as binary anyway but how would i go about bring this out. I will be writing this info to a pipe, which another process will then pick it up and write it to a file. Anyone got any advice?

Here's one of mine: std::string bin(unsigned int i) { std::string result; while(i) { result.insert(result.begin(), i % 2 + '0'); i /= 2; } return result; } -Mike Back to top Julie J. Guest Posted: Mon Feb 23, 2004 10:26 pm    Post subject: Re: Hex to Bin Are you converting it to a string representation? If not, then there is no need to do any conversion (unless you run into endian issues). Presuming that you want to convert it to a string representation: Check your compiler & C library documentation. Some C libraries support something to the effect of itoa (or _itoa) which has a radix (or base). Use 2 to convert a number to a binary string. However, itoa (et al.) are *not* ANSI standard.
