No, with integer arithmetic you can have overflows, which are not specified and where things can badly fail, just like the Ariane 5 explosion: http://www.ima.umn.edu/~arnold/disasters/ariane.html If you try to implement calculations on real numbers in integer arithmetic instead of floating-point, you will have the same kinds of problems (if you want to compare 2 approximations, the equality operator won't work either), except that you will need to handle more difficulties manually. -- Vincent Lefèvre <vincent@xxxxxxxxxx> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Arénaire project (LIP, ENS-Lyon)
