NAME

cxaddf, cxadd, cxaddl, cxaddw, cxaddq, cxaddll, cxadddf, cxaddd, cxadddl, cxadddll - complex addition function with real arithmetic

SYNOPSIS

cc [ flags ] -I/usr/local/include file(cx_s) -L/usr/local/lib -lmcw [ ... ]

#include <mathcw.h>

#include <cxcw.h>

extern void cxaddf (cx_float result, cx_float x, cx_float y);

extern void cxadd (cx_double result, cx_double x, cx_double y);

extern void cxaddl (cx_long double result, cx_long double x, cx_long double y);

extern void cxaddw (cx_float80 result, cx___float80 x, cx___float80 y);

extern void cxaddq (cx_float128 result, cx___float128 x, cx___float128 y);

extern void cxaddll (cx_long_long_double result, cx_long_long_double x, cx_long_long_double y);

extern void cxadddf (cx_decimal_float result, cx_decimal_float x, cx_decimal_float y);

extern void cxaddd (cx_decimal_double result, cx_decimal_double x, cx_decimal_double y);

extern void cxadddl (cx_decimal_long_double result, cx_decimal_long_double x, cx_decimal_long_double y);

extern void cxadddll (cx_decimal_long_long_double result, cx_decimal_long_long_double x,
                                                          cx_decimal_long_long_double y);

NB: Functions with prototypes containing underscores in type names may be available only with certain extended compilers.


DESCRIPTION

Compute the complex sum of x and y, two-element arrays with the real and imaginary parts in that order.

The cx family of functions provide limited support for complex arithmetic when compiler or language support for a complex type is lacking.


RETURN VALUES

Return the sum in the first argument. The arguments may overlap.

ERRORS

Underflow, overflow, and invalid operation are possible.
