It's really a runtime double value. I just checked this on a 10.2 and
10.1 OS and the built tool is returning different values.
It's the API version I'm interested in as I need to check whether a
method is available or not.

You cannot use the above to know what version of OS your Application
is running on. It is a _compile_ time macro not a runtime check.
Try reading over the following tech. note.
http://developer.apple.com/technotes/tn2002/tn2064.html
If you really want to know the OS version, not just if an API / method
is supported then consider using Gestalt [1].
OSStatus status;
SInt32 response;
status = Gestalt(gestaltSystemVersion, &response);
if (status != noErr)
response = 0;
if (response >= 0x1030)
{
// we are running on 10.3 or later
}
