Methods
-
abs(
) → Rational - Returns the absolute value of this num.
-
ceil(
) → Rational - Returns the least integer value that is no smaller than this num.
-
ceilToDouble(
) → double -
Returns the least integer value no smaller than
this. -
clamp(
Rational lowerLimit, Rational upperLimit) → Rational -
Clamps the rational to be in the range
lowerLimit-upperLimit. The comparison is done using compareTo and therefore takes-0.0into account. -
compareTo(
Rational other) → int -
Compares this object to another object.
override
-
floor(
) → Rational - Returns the greatest integer value no greater than this num.
-
floorToDouble(
) → double -
Returns the greatest integer value no greater than
this. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
pow(
int exponent) → Rational -
Returns
thisto the power ofexponent. -
remainder(
Rational other) → Rational -
Return the remainder from dividing this num by
other. -
round(
) → Rational - Returns the integer value closest to this num.
-
roundToDouble(
) → double -
Returns the integer value closest to
this. -
toBigInt(
) → BigInt - Truncates this num to a big integer and returns the result as an BigInt.
-
toDecimalString(
) → String -
toDouble(
) → double - Return this num as a double.
-
toInt(
) → int - Truncates this num to an integer and returns the result as an int.
-
toString(
) → String -
A string representation of this object.
override
-
toStringAsExponential(
[int? fractionDigits]) → String -
Converts a num to a string in decimal exponential notation with
fractionDigitsdigits after the decimal point. -
toStringAsFixed(
int fractionDigits) → String -
Converts a num to a string representation with
fractionDigitsdigits after the decimal point. -
toStringAsPrecision(
int precision) → String -
Converts a num to a string representation with
precisionsignificant digits. -
truncate(
) → Rational - Returns the integer value obtained by discarding any fractional digits from this num.
-
truncateToDouble(
) → double -
Returns the integer obtained by discarding any fractional digits from
this.
Operators

operator %(
Rational other) → Rational -
operator *(
Rational other) → Rational -
operator +(
Rational other) → Rational -
operator -(
Rational other) → Rational -
operator /(
Rational other) → Rational -
operator <(
Rational other) → bool -
operator <=(
Rational other) → bool -
operator ==(
Object other) → bool -
The equality operator.
override
-
operator >(
Rational other) → bool -
operator >=(
Rational other) → bool -
operator unary-(
) → Rational -
operator ~/(
Rational other) → Rational - Truncating division operator.
