A scientific notation number type for idle/incremental games in Rust.
big_number is a lightweight library that provides a simple implementation of big numbers using scientific notation, specifically designed for incremental/idle games where extremely large numbers are common.
The library represents numbers in the form mantissa * 10^exponent where the mantissa is normalized to be between 1.0 and 10.0 (except for zero).
Add this to your Cargo.toml:
[dependencies]
big_number = "0.2.0"use big_number::BigNumber;
// Create big numbers
let a = BigNumber::new(2.5, 10); // 2.5e10
let b = BigNumber::new(3.0, 5); // 3.0e5
// Basic operations
let sum = a.add(b); // Addition
let difference = a.sub(b); // Subtraction
let product = a.mul(b); // Multiplication
let quotient = a.div(b); // Division
// Convert to string
println!("a = {}", a.to_string()); // "2.500e10"
println!("a + b = {}", sum.to_string()); // Result of addition
// Helper methods
let zero = BigNumber::zero();
let class="pl-smi">BigNumber::one();- Simple and lightweight implementation
- Basic arithmetic operations: addition, subtraction, multiplication, division
- Automatic normalization of scientific notation
- String representation for display
- Optimized for performance in idle/incremental game scenarios
