👉 In programming, a "tignum" is a data type used to represent large integers. It allows for the storage and manipulation of very large numbers in a computer system, making it useful for calculations that involve very large values. For example, if you wanted to calculate the factorial of a number, you could use a tignum to keep track of all possible factors and their counts. This would make calculating factorials more efficient than using a traditional loop. In general, tignums are used in
