Question

Hey guys I am using the script tag.

%{..}%

When I do multiplication it seems to work.

up = wrapBenchmark * upperLimit;

But if I do this.

up = wrapBenchmark + upperLimit;

It seems to add the number as a string to the end. Like a string concat. What is the issue here? I just want to add two numbers together. It’s treating everything as a string. Thanks for the help.

Answer 1

Standard String class (java) has overloaded operator + (string concat), and no overloaded operator * (multiply). So, interpreter casts variables to an integer, when cannot invoke multiply on string objects. And groovy is a dynamically typed language, so parameters sends like strings.

To solve your issue write this

up = wrapBenchmark.toInteger() + upperLimit.toInteger();
