NAME

cxcopyf, cxcopy, cxcopyl, cxcopyw, cxcopyq, cxcopyll, cxcopydf, cxcopyd, cxcopydl, cxcopydll - complex copy function with real arithmetic

SYNOPSIS

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

#include <mathcw.h>

#include <cxcw.h>

extern void cxcopyf (cx_float result, cx_float z);

extern void cxcopy (cx_double result, cx_double z);

extern void cxcopyl (cx_long double result, cx_long double z);

extern void cxcopyw (cx_float80 result, cx_float80 z);

extern void cxcopyq (cx_float128 result, cx_float128 z);

extern void cxcopyll (cx_long_long_double result, cx_long_long_double z);

extern void cxcopydf (cx_decimal_float result, cx_decimal_float z);

extern void cxcopyd (cx_decimal_double result, cx_decimal_double z);

extern void cxcopydl (cx_decimal_long_double result, cx_decimal_long_double z);

extern void cxcopydll (cx_decimal_long_long_double result, cx_decimal_long_long_double z);

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


DESCRIPTION

Copy the complex value z, a two-element array 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 copy in the first argument. The arguments may overlap.

ERRORS

None.
