first at all… don’t capitalize a class variable! =\> @emplozeetenure is  
correct

2nd: i don’t remember that there is a to\_d method. use to\_f, because  
float has always double-precision in ruby

3rd: don’t use to\_f better use to\_i… if there compared number anyway  
is a Integer (Fixnum) then better to compare it with a Fixnum.
