However, in most cases, float and double seem to be interchangeable, i.e Using one or the other does not seem to affec. The 53 bits of double s give about 16 digits of precision The 24 bits of float s give about 7 digits of precision. You don't have to guess, just check the jls Int to double is a widening conversion
Widening primitive conversions do not lose information about the overall magnitude of a numeric value [.] conversion of an int or a long value to float, or of a long value to double, may result in. In my earlier question i was printing a double using cout that got rounded when i wasn't expecting it How can i make cout print a double using full precision? The double not in this case is quite simple It is simply two not s back to back
That way you have consistency: A double which is usually implemented with ieee 754 will be accurate to between 15 and 17 decimal digits Anything past that can't be trusted, even if you can make the compiler display it. 1 create the double[] first, add the numbers to it, and add that array to the list (the variable should likely be declared as a list, btw, not an arraylist, unless you're specifically passing it to something that explicitly expects an arraylist.) A similar question for c/c++ (as this may be the top search engine hit)
How can i get double quotes into a string literal? There are two main differences from double
