String Binary to hex number
PostPosted: Thu Jul 08, 2004 8:01 am     Reply with quote
Hello,

Anyone has a snippet on how to convert a string binary say "11000011" to C3 as hex number.

Any help will do.

thanx

I searched on binary AND hex AND convert to find the following. Try using Search one day, it might save you (and US) a lot of time!

I checked back in the forum and found you keep asking repeated questions over an over about conversions between the bases. I would recommend paying attention to what you are being told and learn how to do this rather than trying to get us to do the work every time (Maybe read up on it!)

This is 100% untested and off the top of my head so it may not even compile:

Code:

// st is character array containing binary number of interest
// example st[] = "01011010" which is 0x5A
// i is int8 and result is int16
i=0;
result = 0L;
do {
   shift_left(&result,2,st[i]-'0');
} while(st[++i]);


Add a more detailed stop condition to the do-while loop to prevent more than 16 characters from being evaluated, or whatever is appropriate for your data set.
