how infinity is represented in double in JAVA?

Answer 1

floating point numbers in java are represented in the IEEE457 standard (as in any other languages). when dividing with integers, it can't divide by 0, because of the way a computer divides numbers doesn't allow an integer to hold the result. however, floats can hold infinity, -infinity and even values considered not to be numbers, so there's no need for an exception to be raised.
