  Integer(Float(value)).to_s
end

#safe_to_type(value) ⇒ Object

Integer() does not treat “2.6” the same as 2.6 while 2.6 is a valid Intger() (-> 2), “2.6” is not. Note that “2” is a valid argument for Integer() and that “”.to_i is valid while Integer(”) is not… Circumvent this by first convert with Float() so everything obeys to the same rules
