Re: [Fractint] The Universal Fractal (PDM)
I will definetely give it [arbitrary precision] a try but the problem is the Fractint memory. You are likely right, as different code is likely to be loaded to do the arbitrary precision -- and it may take more memory. However, Fractint's code is organized as "overlays," where unused code (not formulas) is overwritten by code that is in use.
If Fractint's floating point code is overwritten by the arbitrary precision code & they're the same size overlay, you might be OK. Please let me know what you find! - Hal ######################## # hallane@earthlink.net ######################## From: Albrecht Niekamp [mailto:multifrac@t-online.de] Sent: Sunday, January 3, 2016 1:44 PM To: Hal Lane <hallane@earthlink.net> Subject: Re: [Fractint] The Universal Fractal (PDM) Am 03.01.2016 um 17:18 schrieb Hal Lane:

The formula parser in Fractint is not coded to use Arbitrary Precision math. Thanks, Jonathan -- I had forgotten that. The v 20.4 docs don't seem to include that info -- at least I didn't see it.

I will definetely give it [arbitrary precision] a try... Too bad, Albrecht. I'm sorry to have gotten your hopes up about this. I apologize.

Jonathan, Just out of curiosity, do you happen to know whether the Fractint formula parser was written ad hoc -- "from whole cloth" -- or using tools like Yacc and Lex? - Hal Lane ######################## # hallane@earthlink.net ######################## -----Original Message----- From: Fractint [mailto:fractint-bounces@mailman.xmission.com] On Behalf Of Jonathan Osuch Sent: Sunday, January 3, 2016 3:24 PM To: Fractint and General Fractals Discussion <fractint@mailman.xmission.com> Subject: Re: [Fractint] The Universal Fractal (PDM) Hal, Albrecht, The formula parser in Fractint is not coded to use Arbitrary Precision math.
