Hey,
The sqrt function is not doing what I want. This is what I want:
round sqrt(2)
Sigh... never fails. Spend an hour trying to solve a problem, and a minute after you write to the list you find the solution. I need brackets around sqrt. I'm surprised though. I don't understand why it dosn't work without brackets.
Elementary syntax. Function application needs no parentheses and associates left, so sqrt 2 is fine, and what you wrote means (round sqrt) 2 whereas what you want is round (sqrt 2) -- Jón Fairbairn Jon.Fairbairn at cl.cam.ac.uk
