There are no failure exits from this routine. The argument ifail is included for consistency with other routines in this chapter.
6Error Indicators and Warnings
There are no actual failure exits from this routine. ifail is always set to zero. This argument is included for compatibility with other routines in this chapter.
Relative errors in the argument are attenuated when propagated into the function value. When the accuracy of the argument is essentially limited by the machine precision, the accuracy of the function value will be similarly limited by at most a small multiple of the machine precision.
8Parallelism and Performance
s18cff is not threaded in any implementation.
This example reads values of the argument from a file, evaluates the function at each value of and prints the results.
