Divisor Property

Summary

Gets or sets a value used to divide the final result of the output.

Syntax

Objective-C

C++/CLI

Java

Python

public int Divisor { get; set; }

@property (nonatomic, assign) NSUInteger divisor;

public int getDivisor(); 
public void setDivisor( 
   int intValue 
);

public: 
property int Divisor { 
   int get(); 
   void set (    int ); 
}

Divisor # get and set (UserFilterCommand)

Property Value

Value used to divide the final result of the output. This must be a non-zero value. If you want to use floating point values for the matrix elements and the divisor, multiply the matrix elements and the divisor with the same value (for example, 10, 100, 1000). This property only accepts positive values.

   int i, j;
