it would be interesting to focus on own utility for casting/parsing texts and numbers.

small & fast
non standard
error detecting improved
small space complexity $O(1)$

/// cast integer to string (base 10)
void cast_itos10(void* isrc, tbc_u8_t ilen, char* ssrc, slen)
{
   // code
    for (;i2;--i1, --i2) {
        if (i1 == i2) {
            break;
        }
        sdest[i1] ^= sdest[i2];
        sdest[i2] ^= sdest[i1];
        sdest[i1] ^= sdest[i2];
    }
}
