Title: Force result of Fixnum division to integer before using

The [mathn](http://www.ruby-doc.org/stdlib-1.9.3/libdoc/mathn/rdoc/index.html) library overrides Fixnum division to return a rational, so
`1/2 => (1/2)` instead of `1/2 => 0`. Axlsx calls chr on the result of
Fixnum division, which is incompatible. Fix it by forcing to integer.
