In the course of converting some variables from an API, I need to check if the API is returning a string, such as " N/A", and not a number such as "824". This is the code that I'm attempting to use where, if the variable from the API is a number, leave it alone, otherwise, change it to a = (Zero)
$weather["barometer_min"] = (is_numeric($weewxapi[36]) ? number_format($weewxapi[36],0) : "0");
It does not appear to be working, however, it is not throwing any errors. Can anyone guide me in the right direction?
As shown by Syscall, using 3v4l.org, the code works.

The main aspect of CoffeeScript I'd like to see available also for Dart in form of a different, Dart-based language would be less verbosity, less brackets, less Java-style.
Does such solution exist ?
No.
If you don't want to have your field static you can omit the static keyword.
If you don't want to have your field final you can write var or a concrete type instead of the final keyword.
And if you don't want a loop you can omit for, while, forEach, ...

I keep getting this error from this line of code:
result = simplify_path(obj.path_(mlength -2), obj.path_(mlength-1), obj.path(mlength));
result is just a temp variable and the everything has already been defined and works at other places in the code.
simplify_path is a function I defined elsewhere in another file. It is NOT method of my class. I made sure that everything is spelled correctly.
What is going on?
try:
result = simplify_path(obj.path_(mlength -2), ...
obj.path_(mlength-1),...
obj.path_(mlength));

I am getting an error at:
[cardView setOnWeb:[NSURL URLFromString:#"https://www.google.com"]];
The error message says, "No known class field for selector 'URLFromString'."
As far as I can tell from How to make NSURL variable is nil when parsed from null String?, the poster was able (except in the nil case he asked about) to use the basic syntax of [NSURL URLFromString:tmpURL].
So what do I need to change here?
To get NSURL from NSString, use below
NSURL*url=[NSURL URLWithString:yourString];
In your case, it would be
[cardView setOnWeb:[NSURL URLWithString:#"https://www.google.com"]];
^^^^^^^^^^^^^

If you start typing in Xcode something like [selfSpace you see something like this:
What I want now is instead of filtering the results by method names I want to type e.g. NSString and get all methods back that return NSString (like description in this example) or all properties that I can set with NSString.
