Webx= It is a floating-point value to be rounded to an integer Return This method returns the value of the argument rounded to the nearest int value. If the argument is positive or negative number, this method will return the nearest value. If the argument is not a number (NaN), this method will return Zero. WebIn order to force C++ to display our floating-point numbers in the scientific format regardless of the size of the number, we use the format specifier scientific inside of cout. double num = 3.25; // ex = 325 X (10 ^ 25) double ex = 325E25; // using scientific format cout << scientific << num; cout << scientific << ex;
