Implement [ Variable ] Precision Floating Point [ Arithmetic ] in CAS Mode

[profrd]

Since HP Prime CAS is based on XCAS why not implement Variable Precision Floating Arithmetic routines in CAS Mode. Since HP Prime has distinct Home and CAS environments, it makes sense to have two distinct Floating Point implementations. A traditional IEEE Double Precision in Home purely Numerical environment, and desirably a Variable Precision implementation in CAS mode. Its really a Great Task, but we are talking about XXI Century calculators with Hardware good enough for such acomplishment! In every smartphone or tablet one can run XCAS with its Full Potential, including Variable Precision Floating Point, so why Not on HP Prime ?
