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. Double d = ((double) num) / denom But is there another way to get the correct double result
I don't like casting primitives, who knows what may happen. 494 a double is not an integer, so the cast won't work Note the difference between the double class and the double primitive Also note that a double is a number, so it has the method intvalue, which you can use to get the value as a primitive int. 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.)
Has some similar and more in depth answers 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 The first one simply inverts the truthy or falsy value, resulting in an actual boolean type, and then the second one inverts it back again to its original state, but now in an actual boolean value
That way you have consistency: The biggest/largest integer that can be stored in a double without losing precision is the same as the largest possible value of a double It's an integer, and it's represented exactly What you might want to know instead is what the largest integer is, such that it and all smaller integers can be.
