That logic doesn't follow for me. If I replace "float" with "int" in the
above. The conclusion is different. And I conclude that the Endian library
is indeed for both #1 and #2. Hence it seems inconsistent to me that the
library would adhere to different conclusions for some types (i.e. float)
than the other types (i.e. base 2 types).
