"x on its own" is a part of J's mini-language for numeric constants.
Just as 2e3 means 2000 and 0j1 means the square root of negative one,
letters can also be used to express other numeric flavors. See also:

Alrighty, thanks all!
I only tried x: because it was the only entry in the dictionary. (Didn't
see x on its own)

x: converts a result to BigInteger and as you note, the precision of
10^300 is limited. But try
10^300x
or perhaps
<.@o. 10^1000x
+/ (>: i.1000x)^(>: i.1000x) NB. seems to do what you want.

Subject: Is there a BigInteger equivalent in J?
Hi, after seeing some questions that involve finding huge numbers (using
BigInteger in C#, which can store "infinitely large" integers), I tried
doing one in J but got unlimited:
+/ (1+i.1000)^(1+i.1000)
Obviously, it exceeds the range of double, bu
