Albrecht,
Re above ref. 5484-w7a and others generated with Multifractal_12 I am trying to get a definite reply if my stripping of unneeded digits after the dot. alters the calculation of an image. This concnerns variables and commands as they appear on the input screen. The same par-files generate different images compared to Multifractal_10 but that may have othere reasons. I repeat the link which contains some images and the latest edition of the frm https://www.dropbox.com/sh/8ze5mwy9er8gv4x/KqXX9Ge1u_ thanks for your assistance! The short answer is yes, they are different. However, the differences may not be significant, or even visible. You can compare the two images by generating them at the same resolution, load one of the images (using <r>), set debug=50 using the <g> screen, and then load the other image (using <r> again). In addition to the differences shown on the screen, the file cmperr is generated that lists each pixel that is different and what the difference is.

Thank you, Jonathan. That was good advise.. I compared 2 images apparently identical, generated with MFR10 and MFR12. The second version shows more details and simply is the better one, inspite of my stripping unneeded digits. Here is a link, the MFR12 version is first and the results as 3rd image- That clarifies. Thanks, again, Jonathan. Albrecht https://www.dropbox.com/sh/ohfg5f1p9xbk5qc/Kp0gwrb1iv additionally I today did a maximum zoom with mfr12., 3 more are possible. Logically the differences get bigger, the deeper the zoom. The images cpr07 - generated with MFR12 and cpr08 - generated with MFR10 show this drastically. The MFR12 image is still usable and the other one is junk, which proves that the bitstripping enhances precision -at least that´s my interpretation-. Also the generating time with MFR10 is 4min44sec compared to 2min35sec with MFR12. So my efforts to improve MFR10 in addition to the new frms used have not been in vain. Albrecht
