The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

Actually, I would use bitVar = ((byteVar & 0x40) == 0x40);.

Using the != 0 or in your case the !! style will work if you are comparing a single bit, but it will break if you are comparing multiple bits: bitVar = ((byteVar & 0x41) == 0x41); is not the same as bitVar = ((byteVar & 0x41) != 0);.


You may be right
I may be crazy
