Number

The Number object provides constants and methods for working with numeric values, similar to JavaScript's Number functionality.

Overview

declare const Number: {
  (value: unknown): number;
  EPSILON: number;
  MAX_SAFE_INTEGER: number;
  MIN_SAFE_INTEGER: number;
  MAX_VALUE: number;
  MIN_VALUE: number;
  NaN: number;
  NegativeNaN: number;
  NEGATIVE_INFINITY: number;
  POSITIVE_INFINITY: number;
  isFinite: (value: number) => boolean;
  isInteger: (value: number) => boolean;
  isNaN: (value: number) => boolean;
  isSafeInteger: (value: number) => boolean;
  toExponential: (value: number, fractionDigits?: number) => string | null;
  parseFloat: (value: unknown) => number;
  parseInt: (value: unknown, radix?: number) => number;
  toFixed: (value: number, digits?: number) => string;
  toString: (value: number, radix?: number) => string;
};

The Number module includes:

A function to convert values to numbers
Constants for important numeric values
Utility methods for checking number properties
Methods for parsing and formatting numbers

Usage Example

import { Number } from "@rbxts/jsnatives";

// Convert values to numbers
const num1 = Number("123");      // 123
const num2 = Number("123.45");   // 123.45
const num3 = Number.parseInt("0xFF", 16);     // 255

// Use constants
if (num1 < Number.MAX_SAFE_INTEGER) {
  // Safe to use as integer
}

// Check number properties
const isWhole = Number.isInteger(num1);    // true
const isValid = !Number.isNaN(num1);       // true

// Format numbers
const formatted = Number.toFixed(num2, 1); // "123.5"
const binary = Number.toString(num1, 2);   // "1111011"
