I've read about the difference between double precision and single precision. However, in most cases, float and double seem to be interchangeable, i.e. using one or the other does not seem to affec...
En double se pueden almacenar números más grandes y también más decimales. Con los números que has probado no se ve diferencia porque cout << redondea la representación interna para mostrar pocos decimales, y lo que ves en ambos casos es lo mismo, pero internamente no son iguales.
A Double in Java is the class version of the double basic type - you can use doubles but, if you want to do something with them that requires them to be an object (such as put them in a collection), you'll need to box them up in a Double object.
20 Format %lf is a perfectly correct printf format for double, exactly as you used it. There's nothing wrong with your code. Format %lf in printf was not supported in old (pre-C99) versions of C language, which created superficial "inconsistency" between format specifiers for double in printf and scanf.
A double has a much higher precision due to it's difference in size. If the numbers you are using will commonly exceed the value of a float, then use a double. Several other people have mentioned performance isssues. That would be exactly last on my list of considerations. Correctness should be your #1 consideration.
The term double precision is something of a misnomer because the precision is not really double. The word double derives from the fact that a double-precision number uses twice as many bits as a regular floating-point number. For example, if a single-precision number requires 32 bits, its double-precision counterpart will be 64 bits long.

Using long double I get 18/19 = 0.947368421052631578..., and 947368421052631578 is the repeating decimal. Using double I get 0.947368421052631526... However, the former is correct. Why such an inco...
Promise. But, in C++, when calling scanf and printf, the notation used to specify a double is "%lf", and that stands for long float, right? So while a float is less precise than a double, a LONG float (presumedly called long float because it can be "longer" by having more terms) is the same accuracy and therefore essentially the same thing?
