Details:

The Manual says floor(x) returns the largest integer not greater than x.  For
x type double this is what it does.  But for x int32
floor(int32(-44)/10) is -4.  floor(-44/10)  is -5.  And, even worse,
floor(int32(-46)/10) is -5.  This is not
consistent with the Manual or help, but it is what Matlab does!!

So, is this a documentation problem, or could
it behave in a more reasonable way despite Matlab?
