Dear Statalist,

I am trying to write a program to locate the natural log of any number
between 1 and 22026.

In this specific case I am trying the number 22000 but I am having trouble
with the error

sign "obs. out of range" as I try to get to the exact natural log of the
number in question.

Can any one give me any suggestions as to how to handle the problem.
I don't understand why you are not just using the ln function, e.g.

. display ln(22000)
9.9987977


Having said that, your code ran fine for me.  The last few lines of output were

. di `h'
9.9034901

.
. di 2.718281828^`h'
20000.05
