type short won't evaluate in relation?

[djolea]

This simple relation won't evaluate properly if type is short(or char) but if type is int(or long), it will?

Code: Select all

  unsigned short temp;
  short temp1;
  short Set_value;
  short Set_diff;

void main() {
  do {
  
            temp1=temp;

          if(temp1 >= (Set_value+Set_diff)){

                     P0 = 0x00;
                  }

                 else if (temp1 < (Set_value-Set_diff)){

                            P0 = 0xFF;

                          }

}
}

Parenthesis or no parenthesis, relation is true only with int type.
Is this a bug or I do something wrong?

Hello,

Thank you for reporting this problem.
Our developer will solve it as soon as possible.

As a workaround you can cast a temp1 variable:

Code: Select all

    if ((unsigned)temp1 < (Set_value-Set_diff)){
      P0 = 0xFF;
    }

Best regards.

Thanks for the reply, but you didn't test your "workaround" have you?
Yor solution works only if temp1 is positive, and i remind you that it is type of short, not unsigned. Also first part of relation won't evaluate in any case..

Hello,

Yes, you are correct, suggested workaround referees only to this variant (temp1>0).
Solution for this problem will be available in compiler update.

Best regards.
