Im new to C and simply want to format a floating point number but i keep getting the wrong output.



char DiamString[10];

I tried itoa(addr_str,my_address,10); but this outputted a 41 which is 0x31 in decimal :\

I dont think itoa would work for what im doing

OK i tried,
addr_str[0]=my_address;
addr_str[1]=0;
strcat(response_buffer, addr_str)

and now i get the correct output!!

thanks for your tips!!
