Thread: convert uint16_t to char

  1. #1

    convert uint16_t to char

    i have a value in uint16_t that i want to convert in char. How can i do it?

  2. #2
    uint16_t a = 0xFFFF;
    char b = (char) (a & 0x00FF);
    If you notice this notice you will notice that this notice is not worth noticing.

    That just throws away the top most byte. It doesn't do a "conversion". Plus it's the same as just doing:
    char b = (char)a;

    If you want to retain the meaning of every possible uint16_t then it's not going to work, because it's not the same size as a char. If you're only interested in the right most byte, then MTsoul's solution will work.
