WebA class definition encapsulates the code for the allowable operations, or methods, written by the programmer along with the abstract data type, hiding the implementation details there. WebFortran 77 has two different types for floating point variables, called realand double precision. While realis often adequate, some numerical calculations need very high precision and double precisionshould be used. Usually a real is a 4 byte variable and the double precision is 8 bytes, but this is machine dependent. Some
