Follow-up Comment #1, bug #37903 (project octave):
I don't see this as a problem with floor as much as the confusing way that
integers work in Matlab and that we have to conform to for compatibility.
It looks to me as though int32(-46)/10 is -5 because the result of the
division is rounded to nearest instead of just truncating the fractional part.
Note that it is true whether you use in32(-46)/10, which is division by a
double, or int32(-46)/int32(10), which is division of two int32 values.
