very newbie question sorry!
I've written a script which reads numbers from a text file
so far no problem as perl is clever enough to know they're numbers
some of these numbers are expressed in standard form
as for example
5.13E-04
always like that E - digit digit
do i need to write a function to convert to a number or is there one built in i've been scouring the perl cd bookshelf and can't find one
