Hi,

I am beginning my yourney into SMath API. My current bigest problem is how to add a unit to custom function return value.
I am using IPluginLowLevelEvaluationFast interface and in my TryEvaluateExpression implementation I am returning some double value by: result = Entry.Create(TermsConverter.ToTerms(sampleDistance.ToString()));
It works ok, but the question is: how to add unit to result of TryEvaluateExpression, for example standard length measuer - meters ?
Can it be dony by Terms of result of function TermInfo?
Any help will be apreciated

One possible way.

var expr = new List<Term>();
var val = new Term( "10", TermType.Operand, 0 );
var unit = new Term( "'m", TermType.Operand, 0 );

expr.Add( val );
expr.Add( unit );
expr.Add( new Term( "*", TermType.Operator, 2 ) );
