Programming with units

drgriffin · ‎Nov 10, 2009

How well does 14 handle units in programs ? I know earlier versions didn't do so well.

The only real problem I can think of with units in programs is returning multiple values with different units. In this respect Mathcad 14 is the same as before. The only way to return multiple values is in an array, and mixed units are not allowed in arrays.

Second problem - if(...,kg,m)

Well, that's just a problem with SUC. It's not specific to programming.

OK!
kg if ...
m otherwise

So if you're returning multiple values with different units from your program, the last step has to be to divide by the appropriate units to make all the values unitless. Then you have to re-attach (multiply) those units after exiting the program.

It's not specific to programming too.

True. I could write a function with no programming that had the same problem.

It is only one programming tool in Mathcad - Add Line operator.
Local vars we see in the summ operator (i)
While has until operator analog...
