[vtkusers] Set decimal digits in vtkVariant

[Xiaopeng Yang]

Greetings!

 

May I ask how to set decimal digits in vtkVariant? For example, I would like
to set one decimal digit for the double type variable: vol2/1000. 

 

Here is part of my code:

 

std::string message = "Resected volume = ";

message += vtkVariant( vol2/1000 ).ToString();

 

Thanks,

Yang
