Autonomous Problems / I'm dumb

[HatterTingamaji]

Ok so I'm trying to get Autonomous up and running and forgot what I would use to convert from Int to Boolean,
if you can even do that.
I'm not even sure anymore.

While there are casts, the best (most readable and consistent across languages) way to convert a number to Boolean is to us a comparison operator. For example, if you want false when x is zero and true otherwise, use (x!=0).

Edit: that's ok with integers. With floats, you have to watch out for NaN cases. My favorite way to test around all of the cases where x is not a number is to do something like (x==x && x!=0).

Ok so I'm not crazy (well no more so than usual). Thank you!

These exist for a reason!

Double.isNaN(double)
Double.isInfinite(double)

Calling two negatively phrased language-dependent methods is better than one comparison? If there were an isFinite() method, I would consider using it.

Better than using x==x, which seems hacky and is surely platform/implementation dependent. It's better not to introduce hard-to-diagnose bugs in your code.
