Question

I am working on a simple project in Objective-C in Xcode, and I’m getting some stray/ errors about the following line of code:

if(celsius < −273.15) {
    NSLog(@"It is impossible to convert temperatures less than −273.15 degrees Celsius, because this is absolute zero, the coldest possible temperature.");
}

It’s actually only about the first line, but I wanted to give some context.

Any suggestions?

I’ve looked it up here on SO, but everyone else’s error hasn’t had such simple code like mine, although it appears they have a common problem of having the wrong encoding for certain punctuation, perhaps?

It’s got to be just some syntax this in my if statement…

It looks as though it also displays two other stray errors:

Stray ‘\210’
Stray ‘\222’

− != –

Your minus, isn’t a minus.
