If s is null, then a The usual way of getting round this problem is simply to use a type with a larger size and then "chop" off the extra bits (set them to zero). (sometimes called the mantissa) of the floating-point number. When I restore Double.MAX_VALUE and Double.MIN_VALUE I have … 0.1. Just a reminder, in java, Double.MIN_VALUE is actually a positive number, so we have to use -Double.MAX_VALUE at the beginning if we want to keep a double value max as the answer. Advertisements.
