7^(hatddlmZddlmZGddeZGddeZGddeZGd d eZy ) ) Predicate) Dispatcherc(eZdZdZdZeddZy)FinitePredicatea Finite number predicate. Explanation =========== ``Q.finite(x)`` is true if ``x`` is a number but neither an infinity nor a ``NaN``. In other words, ``ask(Q.finite(x))`` is true for all numerical ``x`` having a bounded absolute value. Examples ======== >>> from sympy import Q, ask, S, oo, I, zoo >>> from sympy.abc import x >>> ask(Q.finite(oo)) False >>> ask(Q.finite(-oo)) False >>> ask(Q.finite(zoo)) False >>> ask(Q.finite(1)) True >>> ask(Q.finite(2 + 3*I)) True >>> ask(Q.finite(x), Q.positive(x)) True >>> print(ask(Q.finite(S.NaN))) None References ========== ..
