Exponential expressions in expression nodes

[pandaman]

How would you express exponential expressions using ONLY expression nodes (found in numeric on functions bar)? I have tried 10^x, but the values are not desirable:

1------[10^x]-----11

2------[10^x]-----8

3------[10^x]-----9

4------[10^x]-----14

5------[10^x]-----15

6------[10^x]-----12

I have tried exp(), but it doesn't work...

Try x**y (where y is the exponent).

Wow, it worked! I wonder though why LabVIEW uses ** instead of ^... it would make much more sense to use the former since it works in the Eval f(x) methods. I am very curious as to how ^ operates in expression nodes, since I did receive output.

Thanks for the help :worship:

^ may be reserved for bit exclusive or operations

Oh yea, it's an exclusive OR bit operator....

No problem. Somewhere in the LV documentation there is a page showing all the operators allowed for the formula node & expression node.
