int | n | - the number of values in both the input and output arrays.
|
double | *x | - pointer to the array of input values.
|
double | *y | - pointer to the array of output values.
|
This routine accepts an array of double precision input values, computes sin(x) for each input value, and stores the result in the array pointed to by the y pointer input. It is the responsibility of the calling program to allocate/deallocate enough storage for the output array. This is a relaxed version of sin, suitable for use with fastmath compiler flags or applications not requiring full error handling. Denormal inputs may produce unpredictable results. Special case inputs produce C99 return values. The routine is accurate to better than 1 ulp over the valid input range. This routine may return slightly worse than 1 ulp for very large values between 4e5 and 5e5.
