To me, the concept of the "integer part of a float" isn't all that
well defined. It's really a property of a particular representation
rather than the number itself. You think of it as a string of digits
and chop off the part after the point, then turn what's left back
into a number.

If negative floats were represented in two's complement, for
example, then chopping off the digits after the point would give
a result more like floor than trunc.
