Chris,
In the ctypes wrapper we perform this test on entry:
if (type(main_loop[0]) != float):
#return an error message
That's an imperfect test because lists can contain mixed types. To test an
entire array would be a large performance penalty, so the developer must be
sure that data passed in are all 64-bit float.
Typically data passed into a ctypes wrapper are read from a data store because
the arrays are large. When read from a data store, the developer specifies the
data type like this: newarray = (ctypes.c_double * len(arr))(*arr). So that
ensures all data are of the same type.
