Parser for real floating point values

A TIReal has 8 exponent bits and 14 decimal mantissa digits.

A TIReal entry can be used to form TIComplex or TIComplexPi complex numbers.

Inherited from Dock (via RealEntry, TIEntry, TIComponent):

Method load Loads data into an instance by delegating to Loader methods based on the input's type
Class Variable loaders Undocumented
def calc_data(self) -> bytearray: (source)
overrides tivars.types.real.RealEntry.calc_data

The data section of the component which is loaded on-calc

def decimal(self) -> Decimal: (source)
overrides tivars.types.real.RealEntry.decimal
overridden in tivars.types.real.TIRealPi
Returns
DecimalA decimal object corresponding to this real number
def exponent(self) -> int: (source)

The exponent of the real number

The exponent has a bias of 0x80.

def load_string(self, string: str, **kwargs): (source)
overrides tivars.file.TIComponent.load_string
overridden in tivars.types.real.TIRealFraction, tivars.types.real.TIRealPi

Loads this component from a string representation

If there is no dedicated handler for a component type, all subclasses of the type will be considered.

Parameters
string:strThe string to load
**kwargsUndocumented
def mantissa(self) -> int: (source)

The mantissa of the real number

The mantissa is 14 digits stored in BCD format, two digits per byte.

imag_subtype_id: int = (source)
overrides tivars.types.real.RealEntry.imag_subtype_id
overridden in tivars.types.real.TIRealFraction, tivars.types.real.TIRealPi

The subtype ID this type receives if used as an imaginary part

min_calc_data_length: int = (source)
overrides tivars.types.real.RealEntry.min_calc_data_length

The minimum length of this entry's data

If an entry's data is fixed in size, this value is necessarily the length of the data

overrides tivars.file.TIComponent._type_id
overridden in tivars.types.real.TIRealFraction, tivars.types.real.TIRealPi, tivars.types.real.TIUndefinedReal
