pnpm add @nixat/abacus

Usage

import { abacus } from '@nixat/abacus';

// Format a number with 2 decimal places
const formattedNumber = abacus.format(1234.5678, { decimals: 2 }); // "1,234.57"

// Calculate the average of an array of numbers
const avg = abacus.average([1, 2, 3, 4, 5]); // 3

// Check if a number is prime
const isPrime = abacus.isPrime(17); // true

API

Basic Operations

• isNumber(value: unknown): boolean - Checks if the provided value is a number
• clamp(num: number, min: number, max: number): number - Clamps a number between min and max values
• round(num: number, decimals?: number): number - Rounds a number to the specified number of decimal places
• format(num: number, options?: object): string - Formats a number with specified decimal and thousand separators

Statistical Functions
