Being a f64 fa use expect_double (fa.d);
And being a f64 *fp use expect_double (fp->d);
Did you read the files I mentioned?
At Cygwin such union already exists:
union __dmath
{
__ULong i[2];
double d;
};
union __fmath
{
__ULong i[1];
float f;
};
union __ldmath
{
__ULong i[4];
_LONG_DOUBLE ld;
};
At other architectures a double is a quad and your program is buggy.
