Proving multiplication floor functions
0
$begingroup$
If x, y is bigger than zero (I mean real numbers bigger than 0.) Then why does this always works?
[x][y]<=[xy]<([x]+1)([y]+1)
<= means less or equal to
brackets are floor function

Write $x=n+delta, y=m+varepsilon,$ where $m,n$ are nonnegative integers, and $0ledelta,varepsilon<1.$
