Discrete Math

Prime factors, factorials, permutations, rational fractions, least common multiple, greatest common divisor

Discrete math functions perform operations on integers (…, -2, -1, 0, 1, 2, …), or return discrete output as integers. You can use these functions to factor large numbers, calculate factorials, find permutations and combinations, or find greatest common denominators.
