"exp10" was not found here at The Swamp, not in AutoCAD forums, not at AfraLisp, and only mentioned, not used at CadTutor

Help-file wrong?

exp10() is a function for use in formula fields.

expt is the AutoLISP function you are looking for:

Code - Auto/Visual Lisp: [Select]

1. _$ (expt 10 2)
2. 100

exp10() is a function for use in formula fields....

Sorry - my (really) bad. Via search I found the help side, but ignored that it is related (only) to "cal"

No worries!

Just for fun -

If the expt function didn't exist, you could also use exp in the following way:

Code - Auto/Visual Lisp: [Select]

1. _$ (defun myexpt ( a b ) (exp (* b (log a))))
2. MYEXPT
3. _$ (myexpt 10 2)
4. 100.0
