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.

:format for the conversion of 9...9 (12 digits) to be reversible.

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

:. di string(999999999999, "%13.0g")
:1.000000e+12
:
:. di string(999999999999, "%14.0g")
:999999999999

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