# remquo, remquof, remquol

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 remquof( float numer, float denom, int* quo );
long double remquol( long double numer, long 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 */
``````

### 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 double arguments and returns a double.

## Requirements

remquo, remquof, remquol <math.h> <cmath> or <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
