The floor and ceiling functions predate computers, and there's no
disagreement about their definitions (coincidence or plot?  you be the judge
<wink>).  Python's floor & ceil *are* C's -- like most everything else in
Python's math module, they're tissue-thin wrappers around the platform C
library functions of the same names.  Modulo floating point endcases
(infinities & NaNs & such), their behavior is the same across platforms.
