Binary to ASCII number conversion algorithms

[spoulson]

I'm curious to know what algorithms are known for converting binary numbers to ASCII decimal.

When I first got started in assembly (6502), I came across someone's code that had a 24-bit conversion routine. Since 6502 does not have a mul or div op-code, nor floating point instructions, all computation was done with addition/subtraction and bit shifting. What was most interesting is that the numbers were converted to ASCII starting with the one's place and worked up. I was easily able to adapt it to n-bit number conversion.

Unfortunately, the code to this routine got lost somewhere and I never understood it enough to know how it worked.

So I was curious to know if others know this algorithm or others like it. I'm looking for efficiency.

One more shot... Can anyone provide some input?

Couldn't get much simpiler than this...

#define __toascii(_c) ( (_c) & 0x7f )

Well... all I can say is that doesn't filter out non-ascii control codes. Nor does it convert binary numbers to ASCII decimals.

Can anyone else spare their knowledge? I can't seem to search on this subject anywhere online.

oh so you want to take a binary 0000000000000010 and convert to "2" ? Is that what you want ? Your first post didn't say anything about non-Ascii control codes either.

Something...

#include<stdio.h>
int main()
{
char buffer[8]="0010000";
char iVal={0};

for (int i = 0 ; i < 7 ; i++ )
{
iVal = (iVal << 1) + (buffer[i] & 1);
}
cout<<iVal;
}
return 0;
}
