FixedPointValue class - rohd_hcl library

Constructors

FixedPointValue({required LogicValue integer, required LogicValue fraction, bool signed = false}): Constructs an unsigned FixedPointValue from integer and fraction.
factory
FixedPointValue.uninitialized({bool signed = false}): Creates an unpopulated version of a FixedPointValue, intended to be called with the populator.
FixedPointValue.uninitializedWithSignedness({bool signed = true}): Creates an unpopulated FixedPointValue with the specified signedness.
FixedPointValue.withSignedness({required LogicValue integer, required LogicValue fraction, bool signed = true}): Constructs FixedPointValue from integer and fraction values with a signed option to interpret the MSB of integer as a two's-complement sign bit.

Methods

clonePopulator() → FixedPointValuePopulator<FixedPointValue>: Creates a FixedPointValuePopulator for the same type as this and with the same widths.
compareTo(Object other) → int: Returns a negative integer if this less than other, a positive integer if this greater than other, and zero if this and other are equal.
override
gtBool(FixedPointValue other) → bool: Greater-than operation that returns a bool.
gteBool(FixedPointValue other) → bool: Greater-than-or-equal operation that returns a bool.
isNegative() → bool: Returns true if the number is negative.
ltBool(FixedPointValue other) → bool: Less-than operation that returns a bool.
lteBool(FixedPointValue other) → bool: Less-than-or-equal operation that returns a bool.
negate() → FixedPointValue: Negate operation for FixedPointValue.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toDouble() → double: Converts a fixed-point value to a Dart double.
toFloatingPointValue() → FloatingPointValue: Losslessly converts this value to a minimal generic FloatingPointValue.
toLogic({String? name}) → FixedPoint: Converts this value to a constant FixedPoint signal.
toScaledBigInt() → ({int exponent, BigInt significand}): Returns this exact value as significand * 2^exponent.
toString() → String: Return a string representation of FixedPointValue. Return sign, integer, fraction as binary strings.
override

Operators

operator *(FixedPointValue other) → FixedPointValue: Multiplication operation that returns a FixedPointValue. The result is signed if one of the operands is signed. The result fraction width is the sum of fraction widths of operands.
operator +(FixedPointValue other) → FixedPointValue: Addition operation that returns a FixedPointValue. The result is signed if one of the operands is signed. The result integer has the max integer width of the operands plus one. The result fraction has the max fractional width of the operands.
operator -(FixedPointValue other) → FixedPointValue: Subtraction operation that returns a FixedPointValue. The result is always signed. The result integer has the max integer width of the operands plus one. The result fraction has the max fractional width of the operands.
operator /(FixedPointValue other) → FixedPointValue: Division operation that returns a FixedPointValue. The result is signed if one of the operands is signed. The result integer width is the sum of dividend integer width and divisor fraction width. The result fraction width is the sum of dividend fraction width and divisor integer width.
operator <(FixedPointValue other) → bool: Less-than operation.
operator <=(FixedPointValue other) → bool: Less-than-or-equal operation.
operator ==(Object other) → bool: The equality operator.
override
operator >(FixedPointValue other) → bool: Greater-than operation.
operator >=(FixedPointValue other) → bool: Greater-than-or-equal operation.

Static Methods

populator({required int integerWidth, required int fractionWidth, bool signed = false}) → FixedPointValuePopulator<FixedPointValue>: Creates a FixedPointValuePopulator with the provided integerWidth and fractionWidth, which can then be used to complete construction of a FixedPointValue using population functions.
populatorWithSignedness({required int integerWidth, required int fractionWidth, bool signed = true}) → FixedPointValuePopulator<FixedPointValue>: Creates a FixedPointValuePopulator with the provided widths and signedness.
