A calculator.
The CCCC calculator is a 16-bit postfix calculator that uses fractions as primitives. It includes two special operators, the reciprocal operator and the yet unnamed operator that is the mirror of a division, where instead of putting the first whole number over the second, it makes whole numbers of the numerator and denominator. The Factorization Mode displays the prime factors each number on the stack.
