Sum numbers

Install

npm install math-sum

Usage

import sum from 'math-sum';

sum(5, 5);
//=> 10

sum([1, 2, 3, 4]);
//=> 10

BigInt

import sum from 'math-sum';

sum.bigInt(5, 5);
//=> 10n

sum.bigInt([1, 2, 3, 4]);
//=> 10n

sum.bigInt(1, 2n, 3);
//=> 6n

const largeNumber = 9_007_199_254_740_993n; // Number.MAX_SAFE_INTEGER + 2
sum.bigInt(largeNumber, largeNumber);
//=> 18_014_398_509_481_986n

The sum.bigInt() method accepts both regular numbers and BigInts and always returns a BigInt. Regular numbers are converted to BigInts automatically. This is useful when you need to sum numbers that exceed JavaScript's safe integer range.

[!NOTE] The method throws a RangeError if any value is a non-integer number (e.g., 3.14).
