Description (last modified by gh-mwageringel)

Use parent(a) rather than a.parent() to accommodate floats, ints, etc.

This fixes yet another issue with conversions from symbolic expression to balls, reported by Markus Wageringel at #32871.

In Sage 9.5.beta7:

sage: a = acos(float(1/4) * sqrt(int(5)))
sage: CBF(a)
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
...
AttributeError: 'float' object has no attribute 'parent'

With the fix in this ticket:

sage: CBF(acos(float(1/4) * sqrt(int(5))))
