return 'sum' from a function like '(x) => sum=0; for(i=1;i<=x;i++) sum+=i; sum;'

Hi!

Is it siomehow possible to return a specific value from a function defined in Mages, i.e. if i define a function

   var myfunc = engine.Interpret("(x) => x*2");
   var result = myfunc.Invoke(new Object[] { 7.0 });

then i get 14.0. fine!

but if i’ve got a ‘method’-like function(*1) like:

   var myfunc = engine.Interpret("(x) => sum=0; for(i=1;i<=x;i++) sum+=i; sum;");
   var result = myfunc.Invoke(new Object[] { 100 });

I’d expect that the call returns 5050. but it’s returning 100.

interpreting (i.e. engine.Interpret(…))

    var result = engine.Interpret("sum=0; for(i=1;i<=100;i+=1) {sum+=i;} sum;");

returns 5050.

is it somehow possible to return ‘sum’ from the above defined function *1)?

more info: it returns 100 if there is no variable “sum” defined in Engine.Scope otherwise it returns the value of “sum” (if it is defined in Engine.Scope)

thanks!

Thanks Florain, using “var” does the trick 😃 and BTW: Kudos to MAGES! It’s awesome!!!
