RE: RPGIV math function

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

If  mean finding the value of e^x, if you're willing to accept an arbitrary
level of precision for e, RPGIV has an exponentiation operator: **

You can define e as a constant or assign it to a number and do something
like:

eval result = e ** x

You can alse investigate the ILE math apis or the C math functions which are
both pretty easy to prototype and call.  The ILE api documentation actually
has explicit definitions of the RPG data types necessary to call them.  C
library functions require mentioning the binding directory QC2LE.
