Computes the remainder of two integer values, and stores an integer value with the sign and approximate magnitude of the quotient in a location that's specified in a parameter.

Syntax

double remquo(   
   double numer,  
   double denom,  
   int* quo  
);  
float remquo(   
   float numer,  
   float denom,  
   int* quo  
); /* C++ only */  
long double remquo(   
   long double numer,  
   long double denom,  
   int* quo  
); /* C++ only */  
float remquof(   
   float numer,  
   float denom,  
   int* quo  
);  
long double remquol(   
   long double numer,  
   long double denom,  
   int* quo  
);

Parameters

numer
The numerator.

denom
The denominator.

quo
A pointer to an integer to store a value that has the sign and approximate magnitude of the quotient.

Return Value

remquo returns the floating-point remainder of x / y. If the value of y is 0.0, remquo returns a quiet NaN. For information about the representation of a quiet NaN by the printf family, see printf, _printf_l, wprintf, _wprintf_l.

Remarks

The remquo function calculates the floating-point remainder f of x / y such that x = i * y + f, where i is an integer, f has the same sign as x, and the absolute value of f is less than the absolute value of y.

C++ allows overloading, so you can call overloads of remquo that take and return float or long double values. In a C program, remquo always takes two doubles and returns a double.

Requirements

Function	Required header
`remquo`, `remquof`, `remquol`	<math.h>

For compatibility information, see Compatibility.

Example

// crt_remquo.c  
// This program displays a floating-point remainder.  
  
#include <math.h>  
#include <stdio.h>  
  
int main( void )  
{  
   double w = -10.0, x = 3.0, z;  
   int quo = 0;  
  
   z = remquo(w, x, &quo);  
   printf("The remainder of %.2f / %.2f is %f\n", w, x, z);  
   printf("Approximate signed quotient is %d\n", quo);  
}

The remainder of -10.00 / 3.00 is -1.000000  
Approximate signed quotient is -3
