Have you thought of using a polynomial? For example, perhaps something like this? >.(%*:p:i.5) p. i. 15 1 1 1 3 5 10 18 30 48 74 109 155 214 290 384 or maybe <.(%^i.4) p. i. 17 1 1 2 4 7 12 18 27 38 51 67 87 110 138 169 204 245 That said, note that your original expression is >.(((10+i.25)%7.15)^6.5)%100 and that 10 is approximately 7.15, so this expression is almost >.(((7.15+i.25)%7.15)^6.5)%100 which you could rearrange as >.((1+(i.25)%7.15)^6.5)%100 This drifts the high end somewhat, but I'm not sure how significant that is -- it could be "corrected" in a variety of ways, depending on what it is you want. Also, further algebraic manipulations are also possible, though I'm not quite sure what you really want out of this, and that matters. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
