Iterative exponentiation not evaluated correctly

[Former user]

Originally reported on Google Code with ID 448

Steps to reproduce:
Evaluate 3^3^3

Expected behavior:
Evaluates to 3^3*3, or 3^9, or 27^3, which is 19683

Experienced behavior:
Evaluates to 3^(3^3), or 3^27, which is 7.625597484987e12

Product version:
0.10.1

Operating system:
Windows

Additional Information:
Following the right to left order for operations of the same precedence, exponentiation
is evaluated incorrectly.

The current implementation is actually the correct way. Exponentiation is right associative, i.e. 3^3^3 = 3^(3^3).

See this Wikpedia article.

EDIT: removed typo
