To control the rounding of a block parameter, enter an expression using a MATLAB ® rounding function into the mask field. Programmatic UseIn nearly all cases, the simplest rounding mode produces the most efficient generated code. For a very specialized case of division that meets three specific criteria, round to floor might be more efficient. These three criteria are: Fixed-point/integer signed division. Denominator is an invariant constant. Denominator is an exact power of two.In MATLAB, the functions "floor" and "ceil" can be used to round down and round up, respectively. The "floor" function rounds a given input value down to the nearest integer. For example, "floor (3.7)" would return 3, and "floor (-2.3)" would return -3. The "ceil" function, on the other hand, rounds a given input value up to the nearest integer.The digits functions allows to set the precision of mupad variable precision arithmetic.
