Syntax >>-CEESxATH--(--parm1--,--fc--,--result--)---------------------><
- parm1 (input)
- The input to the hyperbolic arctangent routine. The input range
for real variables is:
For complex variables, parm1 cannot be equal to 1 or -1.
- fc (output)
- A 12-byte feedback code, optional in some languages,
that indicates the result of this service. If you choose to omit this
parameter, refer to Invoking callable services for the
appropriate syntax to indicate that the feedback code was omitted.
The following symbolic conditions can result from this service:
Code Severity Message number Message text CEE000 0 — The service completed successfully. CEE1V1 2 2017 The absolute value of the argument was greater than or equal to limit in math routine routine-name. CEE1V6 2 2022 The value of the argument was plus or minus limit in math routine routine-name. - result (output)
- The result of the hyperbolic arctangent routine. The output range
for functions of real variables is:
Omega varies, depending on the precision of parm1:
