Nick, thanks for this. The main issue is still unclear: is there a
limit on the size of number that can be labeled?
My suggestion of mvencode and the other similar recodes are the way to
go.

:. di string(999999999999, "%12.0g")
:1.00000e+12

:. di string(999999999999, "%13.0g")

:. di string(999999999999, "%14.0g")

:So, -tostring- will work as desired here so long as a suitable
:-format()- is specified.
