how to understand this
posted by apoorva on .
design and implement such a function and use it in a program called part3.c that allows someone to enter two real numbers and an epsilon value (also a real number) and reports if the two numbers are equal (+/- epsilon) or not.
If you were asked this question, how would you try to understand this question;
This is how I looked at it;
I'm asked for two real numbers and an epsilon number.
for example, 5 and 6. epsilon is then 2.
So when I compile my program, my program will do this: 5+2 and 5-2 which is 7 and 3
and 6+2 and 6-2 which is 8 and 4.
Then the result I would have program say would be: No, this is not equal.
Am I reading this right, please help
no, I don't think you are reading it correctly
Here is the logic a,b real numbers, e is some real number.
IF abs(a-b)<=e then YES
