Isn't "long" a long integer? ;-)
>>> help(long)
class long(object)
| long(x[, base]) -> integer
|
| Convert a string or number to a long integer, if possible. A floating
| point argument will be truncated towards zero (this does not include a
| string representation of a floating point number!) When converting a
| string, use the optional base. It is an error to supply a base when

So, converting a float to an integer should really truncate the result,
as is in the documentation.
