It looks to me that the left argument 100 is the maximum number of iterations.
(100&$:) : (4 : 0) defines a verb whose dyad is defined by the (4 : 0) and whose monad is that dyad with a left argument of 100. Another example of such use: root=: %: percent_colon=: 2&$: : root 3 percent_colon 81 4.32675 percent_colon 81 9 ----- Original Message ----- From: miridian <[EMAIL PROTECTED]> Date: Wednesday, January 9, 2008 7:34 Subject: [Jprogramming] (100&$:) in a dyad definition To: Programming forum <[email protected]> > Hi, > > in the J wiki there is > http://www.jsoftware.com/jwiki/Essays/Continued_Fractions > > there is the definition of the qcf dyad that start with > qcf=:(100&$:) : (4 : 0) > > I used qcf to solve a problem in mathschallenge > but I changed (100&$:) to (1000&$:) > > What is the means of (100&$:) ? > > I found $: in the vocabulary as Self-Reference and there > are only monadic case example. > > Luca. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
