Microsoft Excel retains 15 significant digits. To display all 15 digits,you must use a number format (custom or built-in) other than General. TheGeneral number format displays up to 11 numeric characters, with thedecimal point counting as a numeric character. Therefore, if the numbercontains a decimal point, Excel can display up to 10 significant digits,but if the number does not contain a decimal point, Excel can display upto 11 significant digits Adding more numbers to the left of the decimalpoint causes the number to appear in exponential notation.
