Hello,
I'm using java and referring to the "double" datatype. To keep it short, I'm reading some values from standard input that I read in my code as doubles (I would much rather use something like BigInteger but right now it's not possible).
I expect to get double values from the user but sometimes they might input things like: 999999999999999999999999999.9999999999 which I think is beyond an accurate representation for double and get's rounded to 1.0E27 (probably).
I would like to get some pointers on how to detect whether a specific value would be unable to be accurately represented in a double and would require rounding (so that I could refuse that value or other such actions).
Thank you very much
