Inheritance

Constructors

FloatingPoint32Value({required LogicValue sign, required LogicValue exponent, required LogicValue mantissa})
Constructor for a single precision floating point value.
factory
FloatingPoint32Value.uninitialized()
Creates an unpopulated version, intended to be called with the populator.

Properties

bias → int
Return the bias of this FloatingPointValue.
no setterinherited
exponent ↔ LogicValue
The exponent of the floating point: this is biased about a midpoint for positive and negative exponents.
latefinalinherited
exponentWidth → int
The exponent width.
final
hashCode → int
The hash code for this object.
no setterinherited
isAnInfinity → bool
Return true if the represented floating point number is considered infinity or negative infinity
no setterinherited
isAZero → bool
Return true if the represented floating point number is zero. Note that the equality operator will treat FloatingPointConstants.positiveZero and FloatingPointConstants.negativeZero as equal.
no setterinherited
isExponentAllOnes → bool
Test if exponent is all '1's.
no setterinherited
isExponentAllZeros → bool
Test if exponent is all '0's.
no setterinherited
isMantissaAllZeroes → bool
Test if mantissa is all '0's.
no setterinherited
isNaN → bool
Return true if the represented floating point number is considered NaN or "Not a Number".
no setterinherited
mantissa ↔ LogicValue
The mantissa of the floating point.
latefinalinherited
mantissaWidth → int
The mantissa width.
final
maxExponent → int
Return the maximum exponent of this FloatingPointValue.
no setterinherited
minExponent → int
Return the minimum exponent of this FloatingPointValue.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sign ↔ LogicValue
The sign of the value: 1 means a negative value.
latefinalinherited
supportsInfinities → bool
Indicates whether FloatingPointConstants.positiveInfinity and FloatingPointConstants.negativeInfinity representations are supported.
no setterinherited
value → LogicValue
The full floating point value concatenated as a LogicValue.
