Java Datatypes

  • neil_cuajotor + 4 comments

    why is

    if(x>=-32768 && x<=32768)

    Different from:

    if(x >= -Math.pow(2, 15) && x <= Math.pow(2, 15) - 1)

    I tried the first one since its the value given by java documentation but it doesn't work on the last two test cases. can anyone please tell me..

      //if(x >= -Math.pow(2, 15) && x <= Math.pow(2, 15) - 1)
//if(x >= -   32768        && x <=    32768        - 1)
if(x >= -32768 && x <= 32767)

        instead of if(x>=-32768 && x<=32768) try if(x >= -32768 && x <= 32767) I think it's because 0 counts and a bit so the range ends at 32767 instead of 32768

        yes

      short range is from -32768 to 32767 but not from -32768 to 32767

      i think its related to priority x>=-128 && x<=127 we havent write it as x>=-128 && x<=128-1 the reason is <= operator has greater priority then -(minus)
