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
None.
7Accuracy
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
Background information to multithreading can be found in the Multithreading documentation.
s18cef is not threaded in any implementation.
9Further Comments
None.
10Example
This example reads values of the argument from a file, evaluates the function at each value of and prints the results.
