case class RationalNumber(r: Rational, percentage: Boolean = ...)(maybeName: Option[String] = ...) extends ExactNumber, Q, CanAddAndSubtract[RationalNumber], CanMultiplyAndDivide[RationalNumber], Scalable[ExactNumber]

Represents a rational number based on the Rational type, providing various mathematical operations and utilities applicable to rational numbers.

This class extends several traits to enable arithmetic operations such as addition, subtraction, multiplication, and division. It also supports comparisons, conversions, scaling, and power operations.

The class is designed to work seamlessly with precise and exact number representations, ensuring that operations maintain a high level of numeric fidelity.

CONSIDER adding a percentage flag to Real. CONSIDER merging the Rational class into this class (there's no compelling reason to have two separate classes).
