So I am guessing that when I get a float displayed as "inf" this is
not the string it seems to be. Also, it looks like the string value

anyone suggest how I might handle a test case like this?
As Kyle noted, -stringValue returns an NSString, not a char*. You'd
need to compare to @"inf" and print with %...@.
A better way to check for floating-point +infinity and -infinity is to
use the isinf() macro.
if (isinf([number floatValue])) {
NSLog(@"number is +inf or -inf");
}
