A few times while solving a problem where we need to compute ceil values, i have encoured WA when i use ceil(var1/double(var2)) type of expression, for example in this problem a submission of mine was failing on just 2 TCs because of using that expression, and soon as i used a different approach for calculating ceil, i got AC. I wanted to know, what is the fundamental issue behind this inaccuracy?
