# MathMod The function returns the real remainder of division of two numbers. ``` double  MathMod(    double  value,      // dividend value    double  value2      // divisor value    ); ``` Parameters value [in]  Dividend value. value2 [in]  Divisor value. Return Value The MathMod function calculates the real remainder f from expression val/y so that val = i * y + f , where i is an integer, f has the same sign as val, and the absolute value of f is less than the absolute value of y. Note Instead of MathMod() you can use fmod(). Example: ``` #property script_show_inputs   //--- input parameters input double   InpDividentValue  =  10;   // Dividend value input double   InpDivisorValue   =  3;    // Divisor value   //+------------------------------------------------------------------+ //| Script program start function                                    | //+------------------------------------------------------------------+ void OnStart()   { //--- get the real remainder of the division of the numbers entered in the inputs    double res=MathMod(InpDividentValue,InpDivisorValue); //--- print the result in the journal    PrintFormat("Real remainder when dividing %.2f by %.2f = %.2f",InpDividentValue,InpDivisorValue,res);   } ```
