Fractions Type for V2

[thiagomvas]

Summary

Add a Fraction type for exact rational number representation, avoiding floating-point errors.

Motivation

• Floating-point arithmetic introduces rounding errors.
• Useful for exact calculations in number theory, algebra, and symbolic math.
• Enables precise fraction representation (e.g., 1/3, 5/8).

Proposed API

• Fraction(int numerator, int denominator)
• Arithmetic: +, -, *, /
• Reduction to simplest form
• Conversions: double, decimal, string
• Comparisons: ==, <, >, <=, >=

Example Usage

var f1 = new Fraction(1, 3);
var f2 = new Fraction(2, 3);
var sum = f1 + f2; // 1/1
var product = f1 * f2; // 2/9
