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]);
}
