Not when the definition of int(x) is to convert x to an integer
by truncation. Last time I checked, that was the definition.

In the real world, all of the other languages I've ever used in
the past 25 years converted float->int via truncation. Making
Python the exception to the rule would be, IMO, A Bad
Thing(TM).
If you want to round to the nearest integer, then use
int(x+0.5). That's been idiomatic in programming for longer
than I've been around.
