- parm1 (input)
- The input to the exponential base e routine. The input range
varies, depending on the type of function and number:
For Input range Functions of real variables: 
The real part of complex numbers: 
The imaginary part: single floating-point complex numbers: 
The imaginary part: double floating-point complex numbers: 
The imaginary part: extended floating-point complex numbers: 
- 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:
