Formatting output is quite easy. For each identifier or literal
value on the argument list, use:
write (Argument_List);
writeln (Argument_List);
|
The output is right-justified in a field of the specified integer width.
If the width is not long enough for the data, the width specification will
be ignored and the data will be displayed in its entirety (except for real
values — see below).
Suppose we had:
write ('Hi':10, 5:4,
5673:2);
|
The output would be (that's eight spaces before the Hi and three
spaces after):
For real values, you can use the aforementioned syntax to display
scientific notation in a specified field width, or you can convert to fixed
decimal-point notation with:
Value :
field_width :
decimal_field_width
|
The field width is the total field width, including the decimal
part. The whole number part is always displayed fully, so if you have not
allocated enough space, it will be displayed anyway. However, if the number
of decimal digits exceeds the specified decimal field width, the output will
be displayed rounded to the specified number of places (though the variable
itself is not changed).
write (573549.56792:20:2);
|
would look like (with 11 spaces in front):
