Question

Mathcad 14: Display very small numbers.

I am a physicist and I do calculations that result in very small numbers (such as Planck's constant). Mathcad 14 sets the results to zero if the numbers are less than 10**-15. Is there any fix to Mathcad 14 so that I may view the resulting small numbers?

Thank you in advance!

Back to that joule*sec vs kgm�/sec
Don't wonder why units system don't print in the mind of the ordinary layman. So, my horse has two names: "Joule" trying to learn the times table [* sec] ... but the next session I call my horse "kgm�" and now trying to learn the division by "sec".
Maybe that's the way to make a horse speak. Also that's why horse don't speak, because they play football all the times with their names. In fact, horse speak with the neck and materialize their happiness by the roundness of their "apple road". When they turn pancake ... give "Him" + oat. In the worst case: call "Doctor Planck" and if it does not work: call a "Mathcad Units system fan".

If you ask for spicy spaghet, the server might ask you for "how many Scott, Sir " ? You should ask for "a lot of Scott" ... Scott is something like a unit of jalapino pepper.

Actually, it just displays them as zero. It's a dumb default setting chosen years ago by some programmer or engineer that evidently thought anything small didn't really exist.

Click on a blank part of the worksheet, go to format, result, tolerance, and set both values to 307.

Go to Format|Result|Tolerance and set the zero threshold to 307, which is the maximum
