Two people are trying to tell you are making a mistake.
Maybe it is time to pause and think a bit?

Or maybe write a little program with a few values and
using both & and && and see what it does?

The operators can be anything you like, the if checks only
whether the result is nonzero, which means true.

So doing 'if (something && 0x20)' is the same as doing
'if (something && TRUE)' is the same as 'if (something)'.

But, doing 'if (something & 0x20)' will only be true if bit 6
in something is set.
