In case it helps... in the J IDE, if you place the cursor in front of the primitive of interest and press Ctrl+F1, the dictionary page for the primitive will be opened in your browser. Unfortunately the dictionary definitions and examples weren't written with the beginning J user in mind and probably become more useful as you become more experienced (at least that was my experience). > [3] PLEASE HELP ME > > Where can I find information on extended precision.

Searching the J wiki for "extended precision" opens this page: "http://www.jsoftware.com/jwiki/Essays/Extended%20Precision%20Functions"; ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
