Sorry, I don't understand these warning messages...
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.)
