You only seem to be asking about decimal conversion, but here are a couple of hexidecimal techniques (in 'C' language)

Technique 1:

<code>
char nibble_to_char( unsigned digit ) {
if ( digit <= 9 )
return '0' + digit;
else
return 'a' + (digit & 0xF) - 10;
}
</code>

Technique 2:

<code>
char *hexchars = "0123456789abcdef";

char nibble_to_char( unsigned digit ) {
return hexchars[digit & 0xF];
}
</code>

I hope this HTML stuff works!
