A way to split math expressions into multiple lines would be great for presentation of data in a clear way. Ernesto, That was a great feature of Mathcad. I do same as described by Ioan [decompose]. Eventually useful but useless in Smath, because the result from symbolic is in many ways not treatable: very long coefficients, all expressed in rational form. Jean

It is all text after all. On the other hand, if your equation does not fit in a page, are we trying to do too much in one equation? I did run into this issue myself and I ended up separating things

I did run into this issue myself and I ended up separating things Easy in Mathcad, but might turn a blody mess. Much easier to split in components in Smath and lot more elegant. Jean

This was not always easy in SMath (newer feature) and some old codgers yell and scream when the font sizes change in reports . As you said about Mathcad ... Originally Posted by: Jean Giraud That was a great feature of Mathcad... Jean I'm still holding on to Mathcad 15 for dear life (copied all license keys in triplicate) until I can transfer all or most of those sheets over to SMath. I really don't want to go through what you went through on your version of Mathcad rinks:

If something similar to Mathcad 8 Pro <= 11 ... useless. It was demonstrated by Mathsoft, was never used by Collabs [> 125000 exchanges] Hyper delicate to use as you had to first set the ONE line equation then split by place holder/Enter. It could not be used for long symbolic derivatives whereas symbolic expansion couldn't be collected. I used it few times [typical Dirac symbolic integration]. The attached dates back two days ago, just refresh this morning. BTW Andrey, from recollection, I think YOU gave Dragilev Parametric. I have just made good use of it, delicate to make it profitable. Wait few days for Contour Utilities to be attached. Cheers Andrey, Jean Contour_8 Hypersurface.sm (52kb) downloaded 63 time(s).

I didn't use this is Mathcad as well, but as I see from the Internet there was some special operator "+" which allowed to make a line break. If it is a true, then answer is - no, it is done by absolutely different way. Equation uses standard operators. Break is supported for "+", "-" and "*" when it is possible to break equation where user wants. In my point of view implemented approach is very convenient to use. This is implemented for cases when equation is larger then a paper size, so this is the only elegant way to show large equations. I'm still working on this feature, so I expect some improvements will be added soon. Edited by user15 February 2018 20:35:03(UTC) |Reason: Not specified

I can see "split" useful if Smath can download from source a long single line formula. As well useful to export a long single line equation split for export. From within Smath ??? There was a Mathcad continued fraction converter to Wallis algorithm. This one does not work anymore here, my MCD 11 is only a back2back system. Courage Kamarad !

Multiple realeases back to back AND one of my feature requests . Thank you!

From the screenshot in the 6119 build, it looks like it's tied to the math region box (genius). Downloading BETA

Many times, the variable names are long to help define "what" it is. Instead of using "R sub one", I can now "print" equations where it's "R sub insfoam" + "R sub drywall" Makes it easier for the checker to follow. Trust me, I sometimes get lost in your sheets

All these conditions might bring to a long line before you can type ":" and start with a definition line. At this point, the space on the paper for statements along the function definition might become a bit tight and the definition itself might be not printable(anything falling out of paper limit will be cutout in printing). Any chance to have a split at ":=" in order to have the function definition beginning at the left margin of paper? Something like: MyVeryLongFunction(OneNiceArgument, ASecondOne, ThisIsThird, Etc, Etc2, AnotherOne):= |A:= OneNiceArgument + Etc2 |B:= ThisIsThird * AnotherOne |Calculation:= ..... |ToBeContinued... |.... Thanks for any help on this subject Marco

Yes, it is possible. After you have finished composing formula for definition just put the cursor before := and press Ctrl+Enter. This will produce something like Best regards.
