Features

count_factors(number: int) -> list[int] Returns a sorted list of all positive factors of the given number.

digit_sum(number: int) -> int Returns the sum of all digits in the given number.

filter_primes(values: list[int]) -> list[int] Filters and returns prime numbers from a list of integers.

from_percentage(number: int | float) -> float Convert a percentage to a decimal.

gcd(values: list[int]) -> int Computes the greatest common divisor (GCD) of a list of integers.

is_equivalent(ratio1: tuple[int, int], ratio2: tuple[int, int]) -> bool Check if two ratios are equivalent by simplifying both and comparing.

is_perfect_square(number: int) -> bool Determines whether a number is a perfect square.

is_prime(number: int) -> bool Checks whether a number is prime.

is_multiple(number: int, base: int) -> bool Checks if one number is a multiple of another.

lcm(values: list[int]) -> int Computes the least common multiple (LCM) of a list of integers.

mean(values: list[int | float]) -> float Calculates the arithmetic mean (average) of a list of numbers.

median(values: list[int | float]) -> float Computes the median value of a list.

middle(a: int | float, b: int | float) -> float Returns the midpoint of two numeric values.

mode(values: list[int | float]) -> int | float | list[int | float] Computes the mode(s) of a list. Returns a single value or a list of modes.

nth_prime(position: int) -> int Retrieves the n-th prime number (1-based index).

prime_factors(number: int) -> list[int] Get all prime factors of the given number.

simplify_ratio(ratio: tuple[int, int]) -> tuple[int, int] Simplify a ratio by dividing both terms by their greatest common divisor (GCD).

std_dev(values: list[float]) -> float Determine the standard deviation of the values

to_percentage(number: int | float) -> int | float Convert a decimal to a percentage.

triangle_number(index: int) -> int Computes the n-th triangular number.

variance(values: list[float]) -> float Work out the variance of the values.
