Abstraction of integral numeric types. That is, types with no fractional part, including Integer.

The division operation for integral numeric types results in a remainder. Therefore, integral numeric types have an operation, denoted by the remainder operator %, to determine the remainder of any division operation.

if (n%2==0) {
    print("Even!");
}

Division and the remainder operation should satisfy:

  • x == (x/y)*y + x%y

for any instance y other than 0.

All Integral numeric types are also Enumerable, so ranges of integral values may be produced using the measure() and span() operators.

// Iterate from 0 to 100 inclusive
for (i in 0..100) {
    print("The square of ``i`` is ``i^2``");
}

// Iterate all indices of the array, 
// from 0 to array.size-1
for (i in 0:array.size) {
    print(array[i]);
}

Methods
dividesshared default Boolean divides(Other other)

Determine if this number is a factor of the given number.

moduloshared default Other modulo(Other modulus)

The modulo, after dividing this number by the given number. This differs from remainder() in that the result is always positive.

Throws
remaindershared formal Other remainder(Other other)

The remainder, after dividing this number by the given number.
