28. Normalized Scientific Notation

• Normalized scientific notation expects absolute part A^(*) of the number A×10^b to be in the range

  • 1 <= A < 10

• Try the following program to convert numbers from scientific notation to ordinary decimal notation:

  
      #include <iostream>
      #include <iomanip>
      using namespace std;
  
      int main() {
          for (;;) {
              double dbl;
              cin >> dbl;
              cout << setw( 14 ) << showpoint << dbl << '\n';
          }
          return 0;
      }

    (*) the absolute part A is also known as mantissa.
