According to this program any value between ...cde0 and ...cdef is equal to uint64 value of ...cdef which was a big surprise

import numpy
a = numpy.uint64(0x1234567890abcdef)
if a == 0x1234567890abcde0:
    print("BUG!")

Seems like uint64 is converted to float even when it is compared against standard integers which was another big surprise for me.

Probably related to #5612.
