Update your DM42 to the in just published "release candidate" version 3.17, then it will work. I had the same problem before that.

### Re: Calculate closest fraction or sqrt...

Ah, yes, you are right! If I go to more digits it becomes better. Is it possible to change that behavior?

### Calculate closest fraction or sqrt...

Hi there, when i was searching on a program to calculate somehow close fractions or, even better, show a close pi or sqrt value i found this program: https://www.hpmuseum.org/software/qpi/42sqpi.htm Now I'm curious if the behavior on the DM42 is different then on the HP42s. Because I do net get e.g....

### Re: calculate values of Z-table with DM42

With a centered and reduced distribution, it is not wise to use infinity as lower limit. For x <0 the probability is (0.5 - integral from x to 0). For x> 0 the probability is (0.5 + integral from 0 to x). Pierre If i think about it, this makes fully sense. Thank you for this second very valuable hi...

### Re: calculate values of Z-table with DM42

My second question is: What do I insert, if I want to integrate from -∞. Do i just use a very, very big negative number instead of -∞? Basically, yes. The 42S "Programming Examples and Techniques" manual discusses this exact topic on p.127; I'd suggest reading that as there is some explanation and ...

### Re: calculate values of Z-table with DM42

So I wrote the following program representing the formula: 01 LBL "SND" 02 MVAR "z" 03 RCL "z" 04 x^2 05 +/- 06 0.5 07 x 08 e^x 09 2 10 ENTER 11 PI 12 x 13 SQRT 14 / Now I try to integrate this for the variable z from LLIM = -1 to ULIM = 1 with different accuracy. Shouldn't that return ~0.682 (68,2%...

### calculate values of Z-table with DM42

Hi there, as I'm not a native speaker probably there is already the solution for my question in the forums but I'm not able to find it because I search for the wrong terms. I'm a happy new owner of a DM42 and now I'm searching for a solution to calculate the "values of the Z-table" with the calculat...
