div(/)

X/Y

X and Y is a scalar/pair/vector/matrix. If X or Y is a pair/vector/matrix, the other is a scalar or a pair/vector/matrix of the same size.

Return element-by-element division of X by Y. When X or Y is float/double, it returns float/double. When both X and Y are integers, div means integer division, which is the same as applying the floor function after division. For example, 5/2 is 2. If you want "true" division for integers, you can apply the operator ratio "\" instead. Integer division is often used together with the operator mod for grouping data. The results of div and mod should satisfy the relationship: X=div(X,Y)*Y+mod(X,Y).
