DESCRIPTION
Several applications need sine and cosine of the same angle x. These functions compute both at the same time, and store the results in *sin and *cos.If x is a NaN, a NaN is returned in *sin and *cos.
If x is positive infinity or negative infinity, a domain error occurs, and a NaN is returned in *sin and *cos.
RETURN VALUE
These functions return void.ERRORS
See math_error(7) for information on how to determine whether an error has occurred when calling these functions.The following errors can occur:
- Domain error: x is an infinity
- An invalid floating-point exception (FE_INVALID) is raised.
These functions do not set errno.
VERSIONS
These functions first appeared in glibc in version 2.1.ATTRIBUTES
