Converts Integer, String or Float to a String with percentage at the end.
The +opts+ parameter takes a hash of any of these keys:
<tt>:format</tt>, <tt>:precision</tt>,
<tt>:significant</tt>, <tt>:strip_insignificant_zeros</tt>, <tt>:delimiter</tt>,
<tt>:round_mode</tt>
number_to_percentage(100) # => "100.000%"
number_to_percentage(123.400, precision: 3, strip_insignificant_zeros: true) # => "123.4%"
number_to_percentage.("-0.13", format_percentage: " %", precision: 2) # => "-0.13 %"
