Incorrect conversions from int to float and more about libfixmath HOT 4 CLOSED

Hey, this isn't a bug. When you assign integers to a fixed, it's giving it the 
literal binary representation. It's not particularly pretty but C/C++ are 
pretty limited in this regard, there's no way to add in our own number parser 
to correctly parse a fixed point number and the only way to accurately 
initialize is an int.

I think there's an issue ticket somewhere to make this more clear. If you want 
to initialize a number as a float then you'll have to use the conversion 
functions.

The integer value 32767 is actually 0.5 in Q16.

Thanks for the quick reply!

Yeah, to clear things up for anyone else who might read this bug report later, 
you need to do it like this:

fix16_t value1 = fix16_from_int(123);
float value2 = fix16_to_float(value1);

For declaring constant values, you can also use shorthand macro F16(), like 
this:

fix16_t value3 = F16(1234.53); // Works for int, float, double arguments

I would also like to point out that the F16 macro is not part of the code thats 
in the downloads section as of 1/8/13 but it is in the latest commit of the 
repository.
