Modulo by Constant

Perform modulo operation with a constant denominator

Fixed-Point Designer

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.

Examples

Optimize Lookup Tables for Periodic Functions

Reduce the size of lookup tables for functions with symmetry.

Input

X — Dividend

real-valued scalar | vector | matrix | multidimensional array

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

Y — Result of modulus operation

scalar | vector | matrix | multidimensional array

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

Denominator for Modulo Problem — Divisor

10 (default) | real-valued scalar | vector | matrix | multidimensional array

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

Type: character vector

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'

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using Simulink® Coder™.

Slope-bias representation is not supported for fixed-point data types.
