Hello Devon, Yes, I fooled around with this too.
You see, the problem is not in the number of digits but the precision. Here is the current setting of my J Session: 9!:10 '' 16 Which shows I have 16 digits precision ... so if I used your example: 0.123456789112 0.123456789112 There is no problem ... but I am working with really small precision like: 0.0000879 8.79e_5 Unfortunately, if you use do this in conjunction with the clipboard wdclipwrite 0.0000879 0.0000567 15 You'll get "erroneous" data. Of course I already have a work around for this but I was hoping that there are simpler ways to print the proper number. Still, thanks. :) r/Alex -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Devon McCormick Sent: Tuesday, December 04, 2007 8:59 PM To: General forum Subject: Re: [Jgeneral] Engineering notation I assume you know about the global print precision settings? 9!:10 '' NB.
