Parameter types

[oransen]

Should I use get_Units to find out if a Model or User parameter is a double or an integer or...?

[MegaJerk]

You would use TypeName.

MessageBox.Show(TypeName(ParameterNameHere))

 
Example

Dim frank As String 
frank = "1222"

MessageBox.Show(TypeName(frank))

Numeric parameter values internally  are always Double.   

(that's why you need to be careful when compare them for equality).

Units property is useful if user parameter contains text.

In this case Parameter.Units property returns "Text".

In your example you are using VB variables. I was thinking of parameters in a parametric model. I don't think your method would work in that case.

[oransen]

So even integer counts are stored as doubles?

[Vladimir.Ananyev · Accepted solution]

Yes, integers values of numeric parameters are stored as doubles.

You may find out that the e.g. length parameter is "integer" assuming some tolerance: 
if abs(x - round(x,6)) < 0.000001 then <x is integer>

[oransen]

Actually suppose I should know if it is integer or double since I probably create the parameter!

[Vladimir.Ananyev]

Of course we always know if our parameter should be integer or not 

But we should remember that it is rather dangerous directly compare “integer” parameter with the reference integer value:   
       If oParameter.Value = 1 then <do something>
because oParameter.Value could be equal to 1.000000000001
Be careful.
