inherited
pow(int exponent) → Rational: Returns this to the power of exponent.
remainder(Decimal other) → Decimal: Return the remainder from dividing this Decimal by other.
round({int scale = 0}) → Decimal: Returns the Decimal value closest to this number.
shift(int value) → Decimal: Shift the decimal point on the right for positive value or on the left for negative one.
toBigInt() → BigInt: The BigInt obtained by discarding any fractional digits from this.
toDouble() → double: Returns this as a double.
toJson() → String: Converts this to String by using toString.
toRational() → Rational: The Rational corresponding to this.
toString() → String: Returns a String representation of this.
override
