Is there a way to tell if your system is big endian or little endian with out running a program cuz I dont have gcc install? either sudo so i cant sudo install it.

Well I can tell you that if you are using an Intel x86 based system, it is little endian. If you have a PowerPC, (old Apple machines) it is big endian (Apparently that architecture can do both).
Simple. Just analyze the first byte of a multi-byte value, eg:Originally Posted by kiros88
Code:int is_little_endian_machine( void ) { static unsigned long value = 1; static int result = *( unsigned char* )&value == 1; return result; }
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Yes, but is the OP not stating that he/she has no access to a compiler?
Doh! Yeah, I misread that (read: wasn't paying attention)...

Very good - thanks for finding that tabstop. I did not think of using the shell to check, but I will certainly remember this for future use.
