Contract
- assert BigInteger::mod returns non-negative Euclidean result (2) for negative dividend instead of truncated remainder (-1)
- assert BigInteger::remainder preserves truncated division remainder sign (-1)
- assert BigInteger::mod throws InvalidArgumentException on negative modulus while remainder allows it
- assert BigRational::ofFraction automatically simplifies fractions to canonical lowest terms on creation
- assert BigInteger::getLowestSetBit returns null on zero instead of legacy -1
- assert BigDecimal::getFractionalPart returns BigDecimal value 0.45 rather than raw digit string 45
- assert BigInteger::sqrt defaults to RoundingMode::Unnecessary and throws on non-square integers unless RoundingMode::Down is passed
