Inappropriate title

I think using names of medical disorders in an informal figurative sense is offensive because it trivializes the problems people with those disorders face. -Qalle2 (talk) 00:18, 21 February 2023 (UTC)[reply]

I think finding everything offensive is in of itself a mental disorder. 2601:647:5E00:8DA0:8DE3:929E:E9C0:2106 (talk) 05:33, 20 March 2023 (UTC)[reply]

An even more "schizophrenic" number

The page mentions ${\sqrt {f(49)}}$ as a "schizophrenic number", giving its expansion. I've found that ${\sqrt {f(49)-1}}$ is even more "schizophrenic". Here's its expansion (Python code, with newlines inserted and spaces added to match the format in the article):

>>> f = lambda n: 0 if n <= 0 else 10*f(n-1)+n
>>> from decimal import getcontext, Decimal
>>> getcontext().prec = 900
>>> Decimal(f(49)-1).sqrt()
Decimal('
