FORMATTING OUTPUT
You can use the DPP system variable to specify the number of digits
to be displayed and printed for decimal numbers and for integers with
more than 10 digits. In a clear workspace, the OPP system variable is
set to 5 (default value). For exampfe:
:I. 23
1
+!5 , 67 ..... - - - A decimal number with seven digits.
1
~~31+b
L
Only five digits are displayed, and the least significant
digit is rounded off.
The value of OPP does not affect the internal precision of the system.
For example:
- Only five digits are printed.
1?31.~6-

Change the printing precision to seven digits.

internal value of A in the system is seven digits.
Although the OPP system variable allows you to specify the number of
significant digits printed for decimal numbers or integers with more
than 10 digits, there might be times when even more control is needed
for the printed output. The
~
(format) function allows you to
specify the precision and spacing of numeric data. The
~
function
also converts the numeric data to character data. This makes it easier
to print the formatted numeric data with other character data. For
example:
'THE CLASS AVERAGE
