7. Mathew Hendry's macro for binary integer literals    bytes.com

Here's a macro that Mathew Hendry posted back in the year 2000 for achieving binary integer literals that evaluate to compile-time constants: #define BIN8(n)\ (((0x##n##ul&1<< 0)>0)|((0x##n##ul&1<< 4)>3)\ |((0x##n##ul&1<< 8)>6)|((0x##n##ul&1<<12)>9)\ |((0x##n##ul&1<<16)>>12)|((0x##n##ul&1<<20)>>15)\ |((0x##n##ul&1<<24)>>18)|((0x##n##ul&1<<28)>>21)) Now admittedly I don't know how it works mathematically, but still I want to perfect it. The first thing I did was made it more readable (in my own opinion ...

P: n/a rayw I've been trying to write a program that converts an entered number into its binary representation using three different techniques - bit shifting, mod 2, and itoa.. However, I'm getting 'snow blind', and can't get the non-ISO itoa to work as I'd like. The snow blindness makes me think it's me, and not the function! The idea of ...

15. shortening this short code? : binary to int casting    cboard.cprogramming.com

What Salem is referring to is that some processors (in fact most that are not x86) do not accept memory reads from unaligned addresses, e.g. a 4-byte word must be aligned to a 4-byte block in memory. Bus error is the common message from the processor for "unaligned access", but it is sometimes called other things.
