Double is also a datatype which is used to represent the floating point numbers. For example, // ex = 325 X (10 ^ 25) double ex = 325E25; C++ outputs exponential numbers and very large numbers in a format called the scientific format. The strtod function skips all white-space characters at the beginning of the string, converts the subsequent characters as part of the number, and then stops when it encounters the first character that isn't a number.
