Thanks Alex, I'll try them out, and modify multiply to handle an arbitrary amount of matrices. On Wed, Feb 21, 2018 at 11:36 AM, Alexander Burger wrote: > Hi Henrik, > > > For reference, the article / tutorial: > > https://medium.com/technology-invention-and-more/how-to-

Re: Math exp issue?

I think I did it. For reference, the article / tutorial: https://medium.com/technology-invention-and-more/how-to-build-a-simple-neural-network-in-9-lines-of-python-code-cc8f23647ca1 This is the PL solution and it relies on my ext lib here: https://bitbucket.org/hsarvell/ext/overview

Ah, great resource, thanks, let's see if I can get all the way to the finish line on this one now... On Mon, Jan 29, 2018 at 8:25 AM, Alexander Burger wrote: > On Mon, Jan 29, 2018 at 08:14:31AM +0100, Alexander Burger wrote: > > To the question why it returns 101 for

Re: Math exp issue?

Hi since i basically study mathematics at the moment i will implement exp in pure picolisp when i find the time. 2018-01-29 8:25 GMT+01:00 Alexander Burger : > On Mon, Jan 29, 2018 at 08:14:31AM +0100, Alexander Burger wrote: > > To the question why it returns 101

Re: Math exp issue?

Okay, I did a bit of testing it happens when the value of *Scl is 1 or more. You get a similar result if you add or subtract, two or more numbers which are not in the same format; Like one without decimal and the other with a decimal. Make sure all the values are in decimal format with scl set

Re: Math exp issue?

I can't answer why it returns 101 for (exp 1). You can try (exp 1.0) it returns 2718282. This works fine till scl is 8 or less, anything more it simply returns T. (load '@lib/math.l) (exp 1) -> 101 (exp 1.0) ->2718282 (scl 8) (exp 1.0) -> 2688...200 (50 digits number) (scl 9) # or
