iNum Language Guide

Introduction

iNum is an expression-based calculator language that makes mathematical calculations and unit conversions easy and intuitive.

Basic Syntax

1. Data Types

• Integer (Natural): 42, -17
• Float (Real): 3.14, -0.001
• String: "Hello", 'World'
• Boolean: true, false
• Unit Value: 5km, 3.14m, 1024kb

2. Variables

x = 42
name = "iNum"
distance = 5km

3. Arithmetic Operations

• Addition: +
• Subtraction: -
• Multiplication: *
• Division: /

4. Comparison Operations

• Equal: ==
• Not Equal: !=
• Greater Than: >
• Greater or Equal: >=
• Less Than: <
• Less or Equal: <=

5. Ternary Operations

x > 10 ? "big" : "small"
score >= 80 ? "pass" : score >= 60 ? "retry" : "fail"

6. Functions

fn double(x) = x * 2
fn circleArea(r) = pi * r * r
fn calculateTax(amount) = amount > 1000000 ? amount * 0.4 : amount * 0.2

7. Unit Conversions

5km to m        // 5000
1gb to mb       // 1024
(2km + 3km) to m // 5000

8. Built-in Functions

• b64Encode(str): Encode string to Base64
• b64Decode(str): Decode Base64 string
• type(value): Get type of value
• sin(x): Sine function
• cos(x): Cosine function

9. Constants

• pi: Pi (3.141592...)
• e: Euler's number (2.718281...)
