Description
From this conversation on sage-devel :
Using n() sometimes returns the wrong number of digits This is correct: sage: a = n(golden_ratio, digits=5000) sage: len(str(a)) 5001 This is not: sage: a = n(golden_ratio, digits=5000000) sage: len(str(a)) 4999989 Any clue? Jerome Tremblay LaCIM, UQAM

I think that this is in fact a dup of (or at any rate should be solved by the patch at) #10164 :) caused by the BDFL not reading all the posts in a thread carefully enough :) Presumably this fixes it.
By the way, the doctests at that ticket are themselves quite entertaining.

With #10164:
sage: a = n(golden_ratio, digits=5000) sage: len(str(a)) 5001 sage: a = n(golden_ratio, digits=5000000) lsage: len(str(a)) 5000004
So let's close as a dup.

This is related to (and maybe fixed by) #10164.
