Is there a means of obtaining the full list of Math.

's supported in Javascript for Max? Looking that the Max reference manual, they quickly point you in the direction of the 

https://developer.mozilla.org/en-US/docs/Web/JavaScript

 reference manual, ok great but not all the functions for Math are supported by Max (one example the Math.trunc() function). Hoping there is a reference manual for this or something like sending an info message to Max objects to list what goodies they have.

The JavaScript implementation in Max is ECMAScript 6 - so a version from 2015 I believe. All Math object function supported in ECMAScript 6 should work in Max as well.

Thanks Jan, so I do a search for a reference manual of Javascript 6 (ECMAScript 6) and find this:

http://es6-features.org/#NumberTruncation

which lists the Math.trunc() as a valid built in function, however Max (8.5.3) does not support it. For example this simple code of:

js: NOF_NxNR_js2.js: Javascript TypeError: Math.trunc is not a function, line 4

js: error calling function doit [NOF_NxNR_js2.js]

Indicatng the Math.trunc is not supported.

So perhaps Max developers decided to pick and choose which built-in functions to implement? (a bit of sarcasm ;) .

Yes I remember reading somewhere else that Max is supporting version 6 of Javascript.

So the original question still holds, what source of information are developers to use to program in javascript in the Max environment, not the Max/Live specific methods/properties (this is well documented in the Max reference manual) but the javascript language implementation.

So far the only method I have is to look at say:

pick a function I would like to use and cross my fingers that Max supports it.

the js object in Max is es5. for modern js you have 3 options: jweb, node-for-max, or transpilation (possible workflow can be found here -

https://262.ecma-international.org/5.1/#sec-15.8.2

and confirms that for instance the Math.trunc() function does not exist. So this is perfect, documents the Javascript used in Max 8.5.3. I have not dived too deeply in to the js object, so the version 5 will do nicely for the moment. Thanks for your help.

Thanks Rob,
Found the official ECMA Script 5 here:
