Upgraded #

• RationalFormattingExtension.toPercentage: Now takes an optional parameter asRatio to determine whether to treat the input as a ratio value (e.g., 33/100 or 0.33) or a value between 0 and 100 (e.g., 33 out of 100). Defaults to true for backward compatibility.

Added #

• RationalParsing.tryFromString: A version of RationalParsing.fromString that returns null if parsing fails.

Added #

• RationalParsing.fromString: A new utility method that parses strings into Rational objects, supporting the output of Rational.toString (e.g., fractions like "3/4", mixed numbers like "1 3/4") as well as formats parsable by Rational.parse (e.g., integers, decimals, scientific notation). Enables round-trip serialization for JSON and other formats.
