engineering notation literal "3e-3" turning into numbers in J -


i read csv file in j, has numbers in engineering notation, such 3e-3.

in j, can turn literal number ". 

". '3e3' 3000

and

". '3e_3' 0.003

but how turn '3e-3' 0.003

". '3e-3' ill-formed number

you can either guide ". forcing evaluate number giving default value:

0 ". '3e-3'

or charsub offending character:

'-_' charsub ". '3e-3'

i'd recommend first, execution ". potentially dangerous, forcing interpret numbers when that's what's desired best practice.
