tivars.types.real.TIRealFraction

class documentation

class TIRealFraction(TIReal): (source)

Known subclasses: tivars.types.real.TIRealPiFraction

Constructor: TIRealFraction(init, for_flash, name, version, ...)

Parser for real fractions

A TIRealFraction has 8 exponent bits and 14 decimal mantissa digits. However, unlike a TIReal, the floating point value is automatically converted to an exact fraction on-calc.

A TIRealFraction can be used to form TIComplexFraction, TIComplexPi, or TIComplexPiFraction complex numbers.
