the vis-functions are not called

[oweitman]

Describe the bug
in some cases the binding expression is interpreted as eval. then, the resulting javascript want to call the vis function which is not available.

To Reproduce
Steps to reproduce the behavior:

1. create a datapoint with name 0_userdata.0.test1
2. set value to ""181.3999999"" or "181.3999999"
3. in vis create a html-widget
4. as html insert the following expression
   {v1:0_userdata.0.test1;parseFloat(v1);round(1)}
5. in runtime, the result is 0

Expected behavior
the result should be 181.4

Screenshots & Logfiles
browser log (callstack removed)

Yes, the function is called Math.round ... there is no "round" in Javascript

[Apollon77]

An in fact yes bindings are converted into mini javsscripts and eval'ed ...

[oweitman]

yes, there is no round in javascript, but vis owns a binding-function named round

and these functions should be usable as described in the documentation
i guess the same is with the other functions
