Todo List

Class CASConvert

This class is a quick & dirty hack. Therefore it should be written more conscientiously.

Class CASExpression

Implement CASExpression.

Member CASConvert::casobject2variable () const

See the ToDo for CASConvert::vector2variable().

Member CASConvert::vector2variable () const

Rethink if really all the calls to the CASMetaInfo are necessary, because they look more as debugging calls, to find out whether or not the Variable class sets all meta information correctly.

Member LongInt::FractionalPart (const LongInt &r) const

Has to be Implemented properly.

Member LongInt::operator% (const LongInt &r) const

In some cases, it returns wrong values

Member LongInt::Pow (const LongInt &exp) const

Choose a more efficient implementation.

Member LongInt::Power (const CASObject *exp) const

Has to be implemented properly. Chokes on non-integer exponents.

Member Fraction::Add (const CASObject *addend) const

Implementation propably not very efficient. Improve.

Member Fraction::Evaluate () const

Evaluation should also cancel the fraction.

Member Variable::GCD (const CASObject *o) const

Has to be implemented properly. Returns 1 ('one') in any case.

Member Fraction::GCD (const CASObject *o) const

Has to be implemented.

Member Fraction::Invert () const

Has to be implemented.

Member Fraction::InvertIP ()

Has to be implemented.

Member Fraction::IsEqual (const CASObject *o) const

Has to be implemented properly. It should use the cancelled represention of fractions.

Member Variable::IsGT (const CASObject *o) const

Has to be implemented properly. It also relies on the outcome of GetType() to decide which object is greater than the other.

Member Variable::IsLT (const CASObject *o) const

Has to be implemented properly. It also relies on the outcome of GetType() to decide which object is less than the other.

Member Variable::Modulo (const CASObject *divisor) const

Has to be implemented properly. Returns 0 ('zero') in any case.

Member Fraction::Modulo (const CASObject *divisor) const

Has to be implemented.

Member Fraction::operator== (const Fraction &f) const

Has to be implemented properly. It should use the cancelled representation of the fractions.

Member Fraction::Subtract (const CASObject *subtrahend) const

Implementation propably not very efficient. Improve.

Member Sum::Expand () const

Needs to be implemented more efficiently.

Member Product::Expand () const

Needs to be implemented more efficiently.

Member Product::ExplodeSumsIP ()

Make it work with negative exponents as well.

Member Sum::GCD (const CASObject *o) const

Has to be implemented properly. Returns 1 ('one') in any case.

Member Product::GCD (const CASObject *o) const

Has to be implemented properly. Returns 1 ('one') in any case.

Member CASTerm::IsGT (const CASObject *o) const

Implement properly. It simply uses GetType() for comparison.

Member CASTerm::IsLT (const CASObject *o) const

Implement properly. It simply uses GetType() for comparison.

Member Sum::IsOne () const

Has to be implemented properly. Returns false in any case.

Member Sum::Modulo (const CASObject *divisor) const

Has to be implemented properly. Returns 0 ('zero') in any case.

Member Product::Modulo (const CASObject *divisor) const

Has to be implemented properly. Returns 0 ('zero') in any case.

Member Product::Subtract (const CASObject *subtrahend) const

Implement completely in the same manner as Product::Add().
