Renames var to prevent "double is read-only" error

Browse Source 
Under some build systems, the function `double` produces an error:
```SyntaxError: "double" is read-only"```
The error goes away if the variable named `double` inside the function
named `double` is renamed. This commit renames it to `double_var` for
simplicity's sake.
