modulus - hpgDesigns/hpgdesigns-dev.io GitHub Wiki

Modulus is an extremely powerful operator that is useful in many common algorithms.

For instance if it is 11:00 and you want to know what hour it will be in 5 hours on a 12 hour clock you can do the following.

show_message("5 hours from 11:00 is " + string((11 + 5) % 12) + ":00"

You may also want to get whether a number is even or odd.

if (number % 2 == 0) {
  // even
} else {
  // odd
}

It may also be useful to perform some operation every nth iteration of a loop. The following loop will display every 3rd number between 0 and 50.

for (i = 0; i < 50; i++) {
  if (i % 3) {
    show_message(string(i));
  }
}
