Methods

abs() → BigRational
ceil(dynamic toBigInt) → BigRational: Rounds this BigRational towards positive infinity and returns the result as a BigRational.
compareTo(BigRational v) → int: Compares this BigRational with the given BigRational and returns an integer representing the result.
encodeRational() → List<int>
floor() → BigRational: Returns the floor of the BigRational as a BigRational with denominator 1
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
pow(int n) → BigRational: Raises this BigRational to the power of n and returns the result as a BigRational.
remainder(BigRational other) → BigRational: other The divisor Returns a new BigRational representing the remainder of the division.
toBigInt() → BigInt: Converts the BigRational to a BigInt.
toDecimal({int? digits}) → String: Converts this BigRational to its decimal representation.
toDouble() → double: Converts the BigRational to a double.
toString() → String: A string representation of this object.
override

Operators

operator %(BigRational other) → BigRational: Computes the remainder of dividing this BigRational by the given BigRational and returns the result.
operator *(BigRational other) → BigRational: Multiplies this BigRational by the given BigRational and returns the result.
operator +(BigRational other) → BigRational: Adds the given BigRational to this BigRational and returns the result.
operator -(BigRational other) → BigRational: Subtracts the given BigRational from this BigRational and returns the result.
operator /(BigRational other) → BigRational: Divides this BigRational by the given BigRational and returns the result.
operator <(BigRational other) → bool: Compares this BigRational with the given BigRational and returns true if this BigRational is less than the given BigRational.
operator <=(BigRational other) → bool: Checks if this BigRational is less than or equal to the given BigRational.
operator ==(Object other) → bool: The equality operator.
override
operator >(BigRational other) → bool: Checks if this BigRational is greater than the given BigRational.
operator >=(BigRational other) → bool: Checks if this BigRational is greater than or equal to the given BigRational.
operator unary-() → BigRational: Negates this BigRational and returns the result.
operator ~() → BigRational: Rounds this BigRational towards zero and returns the result as a BigRational.
operator ~/(BigRational other) → BigRational: Performs integer division on this BigRational by the given BigRational and returns the result as a BigRational.
