I have simple divisions between integers and I always get another integer as the answer. But I want at least three decimal places. I am using MATLAB R2022b

My divisions look like this,
A=B/C;
Both B and C are integers.

How were B and C created?
If they really are integers (e.g., class int32), then that is the expected result. The default type in Matlab is double, however. So, if you didn't explicitly create them as an integer type/class they will be doubles, and you should get fractional results if the numbers aren't evenly divisible. They might display as if they were integers if they are evenly divisible, however. In this case @Sulaymon Eshkabilov's suggestion will allow you to display it differently if you like.
Examples:
B = int32(3);
C = int32(2);
A = B/C % this will be rounded to the nearest integer
whos % check the type/class of the variables
B = 3;
C = 2;
A = B/C
whos % check the type/class of the variables
B = 4;
C = 2;
A = B/C % this will display as if it was an integer but it is really a double floating point number
whos % check the type/class of the variables

Use format. E.g.:
B = 1;
C = 5;
A=B/C
