Depends what your "expression" is. In Ruby, there's no need to worry
about how big an integer is. Different subclasses of Integer are used
to handle integers of different magnitudes, but that is transparent, so:

a = "123".to_i
=> 123
a.class
=> Fixnum

a = "248578913250896781364890374857878134".to_i
=> 248578913250896781364890374857878134
a.class
=> Bignum

Remember that the variable is just a name pointing to an object and can
point to any object of any class.
