Hi all,
This is my first email to this list; please point me out if
I done anything wrong in this mail like the title format or etc…
I am a newbie to the Boost library. I am really interesting
on the usage of the Boost preprocessor library. I would like to archive 1 of
the thing but I am not sure whether it is possible with Boost preprocessor
library:
Converting the binary number to hexadecimal or
decimal value
Eg: BIN2HEX(011) -> 0x3 or BIN2DEC(011) -> 3
BIN2HEX(1111) -> 0xf or BIN2DEC(1111) -> 15
I had read the C-Template-Metaprogramming-Concepts-Tools-and-Techniques-from-Boost-and-Beyond-C-in-Depth-Series
which tell me how to archive that using template. But what I really want is to done
it with the preprocessor without using any template which will not affect the
run time but only the compile time.
I know that I can use the loop and the arithmetic function
from the Boost library but how do I get the binary number characters count, eg.
COUNT(011) -> 3 or COUNT(0111) -> 4. So that I can use this count with
loop and the arithmetic function to perform the conversion from binary to
hexadecimal or decimal.
Thanks
in advance.

Shin
