Extended Math

extmath (formerly mathapi) aims to provide a lightweight & independent extended mathematical module for Python 3.

Avalable Feature

• Infinite Number Sets
  • prime: 2, 3, 5, 7, 11, 13, 17, ...
    • primary test done by asking does element exists, e.g. 13 in prime.
  • fibonacci: 1, 1, 2, 3, 5, 8, 13, 21, ...
    • Compute fibonacci number at any index by fibonacci(i). It's the same as fibonacci[i], except the list will not growth.
• Duality Value-Function Data Type
  • pi: 3.1416..., or prime-counting function.
  • phi: 1.6180..., or Euler's totient function.
• Subscriptable Function
  • sigma: divisor function, sigma[0] for len and sigma[1] for sum.
• Number Theory
  • factorized: Prime factorization of a number.
  • divisors: Show all positive divisable numbers of a number.
  • Fraction.decimal: Show repeating decimal of a fraction number.
• Arithmetic Function
  • product: Production of a list of numbers.
  • sumpow: Summation of numbers from [1..n], or [1**p..n**p].
  • sumexp: Summation of numbers from [r**0..r**k].
