Default is bits, the digits= keyword argument its for decimal digits instead. Signature: pi.n(self, prec=None, digits=None, algorithm=None): Docstring: Return a numerical approximation this symbolic expression as either a real or complex number with at least the requested number of bits

Whats ambiguous? The call signature is missing, thats a bug. Ideally it would be documented in an INPUT block. On Saturday, March 12, 2016 at 7:26:50 PM UTC+1, Dima Pasechnik wrote: > > sage: pi.n? > Docstring: >Return a numerical approximation this symbolic expression as either >a

sage: pi.n? Docstring: Return a numerical approximation this symbolic expression as either a real or complex number with at least the requested number of bits or digits of precision. this is clearly ambiguous; can it be clarified? (it bites e.g. if one wants to create meaningful
