The program is correct, Walter.
But I can't reproduce it - we have to know the guess(es) introduced for X?
Also, what's the version of the DM42? (SETUP-About)
Cheers, Werner

Joe: because it checks whether the error is less than 1e-12.
1146408/364913 - 3.14159265359 = 1.4e-12

I’m having second thoughts on the top vs bottom-aligned fonts. 2. I'm not sure about having the UFL matrix "top aligned". By it being Bottom Aligned, it makes doing upper/lower case words simple - likewise doing subscripts/superscripts. Upper/lower case is no issue of course, that’s not what I meant...

2. I'm not sure about having the UFL matrix "top aligned". By it being Bottom Aligned, it makes doing upper/lower case words simple - likewise doing subscripts/superscripts. 3. I think it would be best to have the UFL matrix bottom aligned and then just use your DF program to adjust for a top align...

I've picked up some new coding techniques from reviewing your programs. One of the best was the use of subtracting the pressed key code from the key code matrix and doing 1/x on the matrix. If it results in an error (ie, divide by zero) then you know if a valid key was pressed. Much quicker/easier ...

Hi Bill, Yes I realised there’s no easy way of copying a matrix to another state file, but I wanted to make it easy to take a peek. You don’t need UFL though, well not for now, I just put the digit fonts into DF, but the problem remains of course. One of my goals is to have UFL hold all 4 fonts, and...

Yes, your site works, but it does not have the dm42_12 high-res gif, Thomas

I can't seem to be able to install the skins straight from my iPhone. I can select an individual file (say, dm42_12.gif) but the Load button stays greyed out. Am I doing something wrong?
(In the meantime I installed them again using the http server - couldn't wait

Matrix Viewer and rudimentary editor This is a first try, and there are tons of things I will be changing still, but it works quite well as it is. Try it out with the included test matrices M44 and C24x5. before you start MVIEW is packaged with all its subroutines, the digit font matrix DF and a few...

I assign the LO routine to shift R/S and use this to turn off the calculator.

Are you sure you're talking about the DM42..?
