sincos(3M)

DESCRIPTION

These functions are available only for Integrity servers.

sincos() stores the sine of x (x specified in radians) in the object pointed to by sptr and stores the cosine of x in the object pointed to by cptr.

sincosf() is a float version of sincos(); it takes float and float * arguments.

sincosl() is a long double version of sincos(); it takes long double and long double * arguments.

sincosw() is an extended version of sincos(); it takes extended and extended * arguments.

sincosq() is equivalent to sincosl() on HP-UX systems.

USAGE

To use these functions compile either with the default -Ae option or with the -Aa and the -D_HPUX_SOURCE options.

To use sincosw() or sincosq(), compile also with the -fpwidetypes option.

To use any of these functions, make sure your program includes <math.h>, and link in the math library by specifying -lm on the compiler or linker command line.

For more information, see the HP-UX floating-point guide for HP Integrity servers at the following site: http://www.hp.com/go/fp.

RETURN VALUE

sincos(±0,sptr,cptr) stores ±0 in the object pointed to by sptr and 1 in the object pointed to by cptr.

If x is ±INFINITY, sincos() stores NaN in the objects pointed to by its pointer arguments and raises the invalid exception.

If x is NaN, sincos() stores NaN in the objects pointed to by its pointer arguments.

When it raises no other exception, whether sincos() raises the inexact exception is unspecified.

ERRORS

No errors are defined.
