## Number of digits written in exponents

6.9.3.4.1 ExpDigits is an implementation-defined value representing the number of
digit-characters written in an exponent.

The value of ExpDigits is three (3) for the Windows edition of Irie Pascal, and
two (2) for the other editions. So for example

` write('one=', 1.0)`

will write

` one= 1.0E+000`

or

` one= 1.0E+00`

depending on the edition of Irie Pascal being used.
