MixedFraction class
Dart representation of a 'mixed fraction', which is made up by the whole part
and a proper fraction. A proper fraction is a fraction in which the relation
numerator <= denominator
is true.
There's the possibility to create an instance of MixedFraction either by using one of the constructors or the extension methods on num and String.
MixedFraction(
whole: 5,
numerator: 2,
denominator: 3,
);
MixedFraction.fromDouble(1.5);
MixedFraction.fromString("1 1/2");
There also are extension methods to quickly build Fraction objects from primitive types:
1.5.toMixedFraction();
"1 1/2".toMixedFraction();
If the string doesn't represent a valid fraction, a MixedFractionException is thrown.
- Implemented types
Constructors
- MixedFraction({required int whole, required int numerator, required int denominator})
-
Creates an instance of a mixed fraction.
factory
- MixedFraction.fromFraction(Fraction fraction)
-
Creates an instance of a mixed fraction.
factory
- MixedFraction.fromString(String value)
-
Creates an instance of a mixed fraction. The input string must be in the
form 'a b/c' with exactly one space between the whole part and the
fraction.

Methods
-
compareTo(
MixedFraction other) → int -
Compares this object to another object.
override
-
copyWith(
{int? whole, int? numerator, int? denominator}) → MixedFraction - Creates a deep copy of this object with the given fields replaced with the new values.
-
negate(
) → MixedFraction - Changes the sign of this mixed fraction and returns the results in a new MixedFraction instance.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reduce(
) → MixedFraction - Reduces this mixed fraction to the lowest terms and returns the results in a new MixedFraction instance.
-
toDouble(
) → double - Floating point representation of the mixed fraction.
-
toEgyptianFraction(
) → List< Fraction> - Represents the current mixed fraction as an egyptian fraction.
-
toFraction(
) → Fraction - Converts this mixed fraction into a fraction.
-
toString(
) → String -
