Class
When mathn is required, Fixnum's division and exponentiation are enhanced to return more precise values from mathematical expressions.
2/3*3 # => 0 require 'mathn' 2/3*3 # => 2
A Fixnum holds Integer values that can be
represented in a native machine word (minus 1 bit). If any operation on a
Fixnum exceeds this range, the value is automatically
converted to a Bignum.
Fixnum objects have immediate value. This means that when they
are assigned or passed as parameters, the actual object is passed, rather
than a reference to that object. Assignment does not alias
Fixnum objects. There is effectively only one
Fixnum object instance for any given integer value, so, for
example, you cannot add a singleton method to a Fixnum.
