pyfastmath

🚀 pyfastmath is a blazing-fast math utility module for Python, written in C for maximum performance. It includes essential number-theoretic functions like GCD, primality checking, modular exponentiation and many more. Check below for more information about the features.

✨ Features

• gcd(a, b) – Compute the Greatest Common Divisor of two integers
• is_prime(n) – Efficiently check if a number is prime
• mod_exp(base, exp, mod) – Perform Modular Exponentiation: (base^exp) % mod
• lcm(a, b) – Calculate the Lowest Common Multiplicant
• factorial(n) – Calculate the factorial of a positive integer
• ncr(n, r) – Calculate the combination of two number(nCr)
• npr(n, r) – Calculate the permutation of two number(nPr)

⚙️ Installation

After building locally:

pip install .

🧪 Usage

import pyfastmath

print(pyfastmath.gcd(48, 18))         # ➝ 6
print(pyfastmath.is_prime(97))        # ➝ True
print(pyfastmath.mod_exp(2, 10, 100)) # ➝ 24
print(pyfastmath.lcm(48, 18))         # ➝ 144
print(pyfastmath.factorial(5))        # ➝ 120
print(pyfastmath.ncr(5,2))            # ➝ 10
print(pyfastmath.npr(5, 2))           # ➝ 20
