Yes, what makes binary<->hex conversion difficult? It is about the most
natural conversion one can do. Each nibble is a hex character --
simple. No need to break out a calculator or abacus for God's sake.
Anyway, macros or enumerated types will obviously be nicer to read than

you ever seen that diagram that shows how to connect LEDs to the data lines

Offhand I know of no such "binary " con
No way.

ahh
(1<<0)
#define RTB_FLAG_ON_OFF (1<<1)
#define RTB_FLAG_AAC(1<<2)
#define RTB_FLAG_CCB(1<<3)
And then compose the "binary" value using the flag names
ZAP_FLAG_AAB | ZAP_FLAG_CCB
It is quite a bit more to write, but a lot easier to read a few weeks
later.

Well, just adding another base (and a power 2 base, at that) doesn't look
like that much of a feature bloat.

Hello all,
I want to take a floating point number and determine it's binary
