Trying to utilize math....() in a function (javascript).
If this can be done, is there a way to use a function in a query?
e.g. select math.asinh(XXX) as yyy from ...

You can use the Java math for sure: https://docs.oracle.com/javase/8/docs/api/java/lang/Math.html
Example:
var value = java.lang.Math.abs( v );

Thanks Luca.
Still, the question is really about using a function written in Studio/Functions. Lets assume I write a javascript
function in Studio called snug(p), with one parameter. Can I use this in a select statement, e.g. select snug(Sfactor) from Foo...
Saw some discussion about that somewhere. Can this be done?

Indeed. I misread another thread. May be an explicit example should be included in the docs?
Thanks again.

You're right, just added this example:
It will go to the official documentation in the next hours.

Excellent Luca.
How do I use math.js (which I installed) in Javascript functions?
It obviously works in node. What does it take to reference it in a "Functions-function"?

It worked just fine after correcting a mistyping and adding, actually guessing, the phrase: parseFloat(arg). Can someone please
add a few words about this parse-stuff in Functions - in the doc?
// The Math.log() function returns the natural logarithm (base e) of a number.
return Math.log(parseFloat(arg) + Math.sqrt(parseFloat(arg) * parseFloat(arg) + 1));
select arcsinh(foo) from bigFoo group by, etc delivers what's expected.
Cheers,
Tore
