Here are some odd things I found so far.

Why don't the original statement and my function f agree? Which is
correct?
If mine is correct, g provides the digits and h and I are the first and
last halves.
g=: 13 :'}:":x:<.o.10x^y'
g 30

h=: 13 :'(-:y){.g y'
h 30

i=: 13 :'(-:y)}.g y'
i 30

One issue here is that you generated 201 digits. But let's say we round up
for the first half:
b =: <. a % 10x^100
> How to extract the n/2 last digits and asign to a variable ?
c=: (10x^100) | a
Is this what you wanted, or did you want something different?
