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.)
