Let's see some examples:
first:
1140 / 32
ans =
35.6250
second:
int32(1140) / int32(32)
ans =
int32
36
third:
int32(1140 / 32)
ans =
int32
36
So, why division with int32 numbers is not equivalent like in C++?

So, I found solution.
Need to use special division:
idivide(int32(1140), int32(32))
ans =
int32
35

Just wonder what is the risk to overload integer "/" with idivide?
Beside Image Proceesing toolbox where else does MATLAB stock uses integers?

FYI the way MATLAB performs arithmetic on integers is documented here.

Ran in:
int32 is for storing 32-bit integers. The result of the division is rounded to the closest integer value.
int32(32.5)
ans = int32 33
If you want to control how the rounding is handled, use idivide.
