Those are the ones I fixed.

As per my comment:

In C, a floating-point constant is a double, unless explicitly made float by an "f" suffix; to quote the C90 spec:

        An unsuffixed floating constant has type double. If suffixed by the letter f or F, it has type float. If 
suffixed by the letter l or L, it has type long double.

GCC and Clang, when run with -Wshorten-64-to-32, will warn about assigning a double value to a float, as well as 
assigning a 64-bit integer value to a 32-bit integer.  (I wish there were a general -Wshorten, that *also* warned about 
32-bit integer values and 16-bit integers and about 16-bit integer values and 8-bit integers, so that those warnings 
will be caught with GCC/Clang as well as MSVC.)
