FixedPointValuePopulator<FxvType extends FixedPointValue> class

A populator for FixedPointValues, a utility that can populate various forms of FixedPointValues.

Constructors

FixedPointValuePopulator.new(FxvType _unpopulated): Creates a FixedPointValuePopulator for the given _unpopulated FixedPointValue.

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
ofDouble(double val) → FxvType: Constructs FixedPointValue from a Dart double rounding away from zero.
ofFixedPoint(FixedPoint fp) → FxvType: Extracts a FixedPointValue from a FixedPoint's current value.
ofLogicValue(LogicValue val) → FxvType: Construct a FixedPointValue from a LogicValue
populate({required LogicValue integer, required LogicValue fraction}) → FxvType: Populates the FixedPointValue with the given integer and fraction, then performs additional validation.
random(Random rv, {bool subNormal = false, bool genNormal = true, bool genSubNormal = true, FxvType? gt, FxvType? lt, FxvType? gte, FxvType? lte}) → FxvType: Generate a random FixedPointValue, using random seed rv.
toString() → String: A string representation of this object.
override
widen(FxvType fxv) → FxvType: Constructs a FixedPointValue from another FixedPointValue with by widening the integer and/or fraction widths.

canStore(double val, {required bool signed, required int integerWidth, required int fractionWidth}) → bool: Return true if double val to be stored in FixedPointValue with integerWidth and fractionWidth lengths without overflowing.
