This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
in the program below I have initialised two variables with int values and decrement the variable f by one each repetition f eventually becomes 0 which creates a ArithmeticException and I get the desired result for the exercise the code is below
the resultant output is 120/5 is 24 120/4 is 30 120/3 is 40 120/2 is 60 120/1 is 120 cannot devide by zero ---which is what I expectd
I changed the variable f to a double :-
and got this 120/5.0 is 24.0 etc..... 120/1.0 is 120.0 120/0.0 is infinity
Would someone be kind enough to tell me what causes the difference in output when a varialbles initialiser is changed , please

Being able to denote infinity as a specific value is useful because it allows operations to continue past overflow situations. Operations with infinite values are well defined in IEEE floating point.
