__eq__()

template<typename Container , typename Poly >

bool SymEngine::MSymEnginePoly< Container, Poly >::__eq__ ( const Basic &  o ) const

inlineoverridevirtual

Test equality.

A virtual function for testing the equality of two Basic objects

Deprecated:

Use eq(const Basic &a, const Basic &b) non-member method

Parameters

o	a constant reference to object to test against

Returns

True if this is equal to o

Implements SymEngine::Basic.

compare()

template<typename Container , typename Poly >

int SymEngine::MSymEnginePoly< Container, Poly >::compare ( const Basic &  o ) const

inlineoverridevirtual

Returns -1, 0, 1 for this < o, this == o, this > o. This method is used when you want to sort things like x+y+z into canonical order. This function assumes that o is the same type as this. Use __cmp__ if you want general comparison.

Implements SymEngine::Basic.
