Description

The Modulo by Constant block performs the modulo operation (remainder after division) with a constant denominator.

The Modulo by Constant block uses an algorithm that is functionally similar to a Barrett Reduction. The division operation is computed via a multiplication by inverse, which generally results in better performance on embedded systems.

Optimize Lookup Tables for Periodic Functions

Reduce the size of lookup tables for functions with symmetry.

Ports

Input

expand all

Dividend, specified as a real-valued scalar, vector, matrix, or multidimensional array.

If X is a fixed-point data type, it must use binary-point scaling. Slope-bias representation is not supported for fixed-point data types.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | fixed point

Output

expand all

Result of modulus operation, returned as a scalar, vector, matrix, or multidimensional array.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | fixed point

Parameters

expand all

Divisor to use for the modulus operation, specified as a positive, real-valued, finite scalar, vector, matrix, or multidimensional array.

Programmatic Use

Block Parameter: Denominator

Values: MATLAB® expression that evaluates to a positive, real-valued, finite fixed point or numeric value
Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point
Default: '10'
