Hi all!

Maybe this is a stupid question, but I'm just starting with SMath.

I searched also in forums but didn't find a similar topic..

I perform my calculations in SMath using always units, very interesting and useful. But now I need just the number, the value without units. What I do now is just dividing it by '1' and the unit XD

Any other method or function more professional? :P

Thanks a lot!

In fact, this is the only professional way to do it, because this way you can control and display the unit to be used. Just suppressing the unit would force the reader to make assumptions on what unit has been used to derive the numerical value. The experienced reader knows that always base units are used (e.g. for plotting) but it is better to explicitly specify them.

Thanks, Martin..

It's exactly the way I work.

But now I want to export data to an Excel sheet, and afterwards to treat that data as numbers without unit (Excel works like that).. so instead removing the unit in Excel, I was just wondering if in SMath would be a function to do it before exporting

Best regards,

Assuming you have a table with columnwise uniform units, then the following approach provides full control:

That is incoherent with unitless maths.
1. It can't be QA whereas the unit system sub-processes.
2. Advanced maths [symbolic, solvers ..] don't take units.

Engineering formulas are already given in corresponding units [SI , ...]

1. Vincenti is coded 'km' superb
