Error computing expressions with logarithms entered with button without brackets

[calderov]

What Happened?

Computing ln(5) / ln(2) returns an incorrect result.

The same happens for log(5)/log(2) although log(5) and log(2) are correct in isolation.

Steps to Reproduce

1. Open Calculator
2. Compute ln(5)/ln(2)
3. You will get 1.975950833 as a result, this is wrong as the correct result is 2.321928094.

Expected Behavior

The expression ln(5)/ln(2) should return the correct result.

I am not getting this issue using the Calculator compiled from source or from last release version (8.0.0). This is when typing "ln(5)/ln(2)" into the entry manually.

However, when generating the expression using the ln function and divide buttons, you do get the wrong answer.

Looks like without the brackets the calculator is interpreting "ln5/ln2" as "ln(5/ln(2))", so it is a precedence issue.

Thanks for picking this up @jeremypw
