Hi

I’m wondering why Math.trunc(x) does not work in AppLab?

For example:  
var x = 2.2;  
//x = Math.round(x);  
x = Math.trunc(x);  
console.log(x);

Math.round works but Math.trunc does not work

Thanks

I dont think it is supported on AppLab. I don’t see it in the documentation. [https://docs.code.org/applab/](https://docs.code.org/applab/)

Where can I request that AppLab add Math.trunc into the pool of commands?

Thoughts?

Math.floor(num) works for me! Not in the docs, but a vanilla javascript function.
