I’d want to get rid of one @ in the chain
at the expense of introducing rank
<@( [: "."0 @ ; <@":"0)\ *: >: i. 15

… and depending on what you want, there might be a better approach: parse the 
numbers, raze the strings, itemize the characters, and interpret each as a 
digit.
<@( [: ". @ ,. @ ; <@":"0)\ *: >: i. 15

NB. Generate increasing lengths of integer squares & store in m:

NB. Convert each box to characters, remove blanks, convert back to
integers, separate the digits, store in p, & display:

]p=.sep ea ". ea rab ea":ea ,ea m

NB. UhOh! there are floating-point numbers in p! should all be integers!

datatype each p

│integer│integer│integer│integer│integer│integer│integer│integer│integer│integer│floating│floating│floating│floating│floating│


NB. What is with the floating point numbers 8.11328 in p? They should be
all integers!


Also, is there a better way to generate increasing length sets of a vector?
