+        <description>Implementation of rational number arithmetics for .NET
+
+Supported features:
+
+- implicit conversions - rationals integrate seamlessly with other number types
+- unlimited precision - rationals use BigInteger inside
+- canonical form - each rational can have its canonical form (irreducible fraction where denominator is always positive)
+- comparison & equality
+- multiple formatting options - ToString("C") (canonical form), ToString("W") (whole + fractional part), or normal fraction format
+
+Example usage:
+
+Rational left = (Rational) 1 / 2;
+
+Rational right = (Rational) 1 / 4;
+
+Rational sum = left + right; // equals to: 3 / 4
