int number range

1. Randomly take an int range of one number, such as 0-3 to take 0,1,2,3, including 0 and 3Common error notation:because the range of Javascirpt math.random () is [0,1], contains 0, does not contain 1, the error is written, because Math.floor is

A question arises:In 32-bit machines, the int range is-32768 ~ 32767Instead of-32767 ~ 32767-How can I get 32768? ========================================================== ============Message Group: Group/record ()=======================
