no setter, override

equality → Equality<double>

Returns an equality relation.

no setter, inherited

field → Field<double>

Returns a mathematical field, if available.

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

isNullable → bool

Returns true, if this DataType supports null values.

no setter, inherited

max → double

Returns the maximum finite value of this value.

no setter

min → double

Returns the minimum finite value of this value.

no setter

minPositive → double

Returns the smallest positive value larger than zero.

no setter, override

name → String

Methods

cast(dynamic value) → double

Casts the argument to this data type, otherwise throw an ArgumentError.

inherited

castList(Iterable<Object?> elements) → List<double>

Casts an existing iterable to this data type.

inherited

comparator(double a, double b) → int

Returns a Comparator that compares one element to another.

inherited

copyList(Iterable<double> iterable, {int? length, double? fillValue, bool readonly = false}) → List<double>

Creates a fixed-length list copy of the iterable, possibly with a modified length and if necessary populated with fillValue.

inherited

emptyList(int length) → Float64List

Internal method to create an empty typed-list of the requested length.

newList(int length, {Map1<int, double>? generate, double? fillValue, bool readonly = false}) → List<double>

Creates a fixed-length list of this data type.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

readonlyList(Float64List list) → Float64List

Internal method to make the typed-list read-only.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
