Importance of irrational numbers in computer science Computers can only deal with a few rational numbers. Why is it important as a computer scientist to deal with irrational numbers?
The question displays a fundamental misunderstanding about the nature of what can be done with computers.  To correct this misunderstanding, I suggest getting a copy of the computer algebra software Maple and trying the commands

expand((1+sqrt(2))^5);
sin(Pi/4);


If computers can only deal with rational numbers, how do you explain the results?
