Bug Reports

Hi,

Natural Logarith Ln() is suggested as a dropdown menu but it doesn’t work.

Regards

NOTE: This is a self reminder for me on where to find the available functions and syntax.

Math.Log in .NET has LN as Log with one argument so perhaps Ln() could be replaced with it:

Just FYI - this is also refefenced in the manual. Other expression fields use this syntax too.

PrePoMax uses Nclac: Functions · ncalc/ncalc Wiki · GitHub
And you are right, Ln is not supported. I removed it from the list of values.

I will see if I can add it as a new function.

I have added Ln() back to the list and also added a function for its evaluation. It will be available in the next PrePoMax version.

I also have it. And once it appears, any further equations in the session will show this error:
