Methods

abs() → FloatingPointValue
Absolute value operation for FloatingPointValue
inherited
compareTo(Object other) → int
Floating point comparison to implement Comparable<>
inherited
isNaN() → bool
Return true if the represented floating point number is considered NaN or 'Not a Number' due to overflow
inherited
isNormal() → bool
Return a Logic true if this FloatingPointVa;ie contains a normal number, defined as having mantissa in the range [1,2)
inherited
negate() → FloatingPointValue
Negate operation for FloatingPointValue
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDouble() → double
Return the value of the floating point number in a Dart double type.
inherited
toMappedSubtype() → FloatingPointValue
Converts this FloatingPointValue to a FloatingPointValue with the same sign, exponent, and mantissa using the constructor provided in subtypeConstructorMap if available, otherwise using the default constructor.
inherited
toString({bool integer = false}) → String
Return a string representation of FloatingPointValue. if integer is true, return sign, exponent, mantissa as integers. if integer is false, return sign, exponent, mantissa as ibinary strings.
