Hi, this is my first post to the list. I would appreciate some help understanding how J evaluates the following:
100 (32&+) 100 The answer is 3300. Since no multiplication symbol appears I am somewhat lost how this phrase is being interpreted. I understand (32&+) to be a monad so I presume there is a definition in the dictionary which sets out how such phrases are used dyadically which I have yet to come across. Any pointers would be appreciated. Thanks, Patrick PS The background to this question: I recently discovered J and have worked my way through the primer. One thing I am having a bit of trouble with is atop @. My thinking was that if I leave it out and I understand what J does without it I can then understand why atop is needed. Using the centigrade Fahrenheit example: 32&+@(1.8&*) Compared with: 32&+(1.8&*) I was scratching my head trying to understand what was happening when the atop was left out, eventually tracing it to a phrase similar to the one in the question. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
