§10.11. Mathematics

It is uncommon, but not absolutely unheard-of, to need to do detailed mathematical calculations in interactive fiction.

The Fibonacci Sequence demonstrates the calculation of a series of numbers; Sieve of Eratosthenes shows off how to calculate the prime numbers within a certain range.

Number Study demonstrates conditional relations between numbers.

*ExampleNumber Study
The parity and joint magnitude relations explored.

*ExampleThe Fibonacci Sequence
The modest Leonardo Fibonacci of Pisa will be only too happy to construct his sequence on request, using an array.

*ExampleSieve of Eratosthenes
The haughty Eratosthenes of Cyrene will nevertheless consent to sieve prime numbers on request.
