Contrato
- BigRational::of(1, 3) takes only 1 argument and silently evaluates to 1/1; fractions require ofFraction(1, 3) or of('1/3')
- BigRational::ofFraction(2, -4) eagerly normalizes to -1/2 with strictly positive BigInteger denominator
- BigRational::ofFraction(1, 0) throws brick/math's DivisionByZeroException implementing MathException, not native DivisionByZeroError
- toBigDecimal() on non-terminating rational 1/3 throws RoundingNecessaryException; terminating 1/4 returns 0.25
- toScale(2) on 1/3 without RoundingMode defaults to Unnecessary and throws; explicit RoundingMode produces 0.33
- BigRational::plus(BigInteger) succeeds (1/3 + 5 = 16/3), but BigInteger::plus(BigRational) and BigDecimal::plus(BigRational) throw RoundingNecessaryException
- BigRational::power(-2) inverts and exponentiates ((2/3)^-2 = 9/4), while BigInteger::power(-2) and BigDecimal::power(-2) throw InvalidArgumentException
