remquo(3M) remquo(3M)

NAME

remquo( ), remquof(), remquol(), remquow( ), remquoq() - remainder function with quotients

SYNOPSIS

#include <math.h>

double remquo(double x, double y, int *quo);

HP Integrity Server Only

float remquof(float x, float y, int *quo);

long double remquol(long double x, long double y, int *quo);

extended remquow(extended x, extended y, int *quo);

quad remquoq(quad x, quad y, int *quo);

DESCRIPTION

The remquo() function computes the same remainder as the

remainder() function. In the object

pointed to by quo it stores a value whose sign is the sign of x/y and whose magnitude is congruent mod 2

the magnitude of the integral quotient of x/y, where n is 7 on HP-UX systems.

Integrity Server Only

remquof() is a float version of remquo(); it takes float ﬁrst and second arguments and returns a

float result.

remquol() is a long double version of remquo(); it takes long double ﬁrst and second argu-

ments and returns a long double result.

remquow() is an extended version of remquo(); it takes extended ﬁrst and second arguments and

returns an extended result.

remquoq() is equivalent to remquol() on HP-UX systems.

USAGE

To use these functions, compile either with the default -Ae option or with the -Aa

and

-D_HPUX_SOURCE options.

To use (for Integrity servers) remquow() or remquoq(), compile also with the -fpwidetypes

option.

Make sure your program includes <math.h>. Link in the math library by specifying -lm on the compiler

or linker command line.

RETURN VALUE

The

remquo() function returns the same values and raises the same exceptions as remainder() .

ERRORS

No errors are deﬁned.
