remquo

#include <math.h>float remquof(float a, float b, int *quo);double remquo(double a, double b, int *quo); long double remquol(long double a, long double b, int *quo);

remquo( ), remquof( ), and remquol( ) were added by C99.

The remquo( ) family of functions returns the remainder of a/b. On return, the integer pointed to by quo will contain the quotient.

A related function is remainder( ).
