class SymEngine::Infty : public SymEngine::Number ¶

This class holds “infinity” It includes a direction (like -infinity).

Public Functions

Infty(const RCP<const Number> &direction)¶: Constructs Infty using the sign of _direction

Infty(const Infty &inf)¶: Copy Constructor.

bool is_canonical(const RCP<const Number> &num) const¶

Canonical when the direction is -1, 0 or 1.

Return: true if canonical

hash_t __hash__() const¶

Return: size of the hash

bool __eq__(const Basic &o) const¶

Equality comparator

Return

whether the 2 objects are equal

Parameters

o: - Object to be compared with

int compare(const Basic &o) const¶: 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.
