Narcissistic numbers are also known as:
::* [[Armstrong numbers]]
::* perfect[[Perfect digital invariant]] (Madachy 1979)
::* plus[[Plus perfect numbers]] (Hardy 1993)
 
Narcissistic numbers are similar to ''powerful numbers''.   Powerful numbers are integers that are equal to some fixed (integer) power of their digits.

:::: My main concern was the use of ''a positive number'''   (or number).   That has been corrected.   As far as the other names, people searching for an algorithm for Armstrong numbers (or the other names) would now be able to find it easier. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 21:35, 7 March 2014 (UTC)

==D language comparative speedup?==
How about astatement like "The faster version has an $n times speedup over the first"? --[[User:Paddy3118|Paddy3118]] ([[User talk:Paddy3118|talk]]) 13:48, 7 March 2014 (UTC)

Hi Hout. You were so busy blaming the language you chose to demonstrate for the problems with your code that you forgot to uncomment the line which at least makes it return 25 numbers. :) --[[User:Nig|Nig]] ([[User talk:Nig|talk]]) 18:20, 26 October 2020 (UTC)
