arg n must have a value in the range ±88.029691. A number larger
than
+88.029691 will result in
an
overflow error message. A number smaller
than
-88.029691 will yield a zero result.

?EXP(1)
EV-EXP(2)
EBIIIEXP(50.24)
?EXP(S9.0296919)
?EXP(-88.0296919)
?EXP(SS.029692)
?EXP(-SS.029692)
Prints 1
Prints 2.71828183
Results in EV=7.3890561
Results in EB=6.59105247E+21
Largest allowable number, yields 1.70141183E+38
