In practice, this means that if you assign a value of 2.5 to variable A and set the
number of decimal places to 0, it will be shown as 3, but if you multiply A by 2, the
result shown will be 5, not 6.
Therefore, TextMaker also comes with a function called ROUND for real rounding.
It can be applied as in the following example:
A = ROUND ( 2.5 ; 0 )
The function’s arguments are the value to be rounded and the number of decimal
places to which it is to be rounded, separated by a semicolon. In the example above
the value of 3 is assigned to the variable A.
You will find detailed information about all TextMaker’s computational functions
in section “Formulas and functions” beginning on page 371.
Updating calculations
When you enter or edit a calculation with Insert > Calculation and then confirm
with OK, TextMaker automatically updates all the calculations in the document.
However, in certain situations the results of calculations can appear “outdated”. For
example, if you paste from another document a segment of text containing variables
that are also used in the current document, TextMaker inevitably displays false
results on the screen.
The command Tools > Update Fields (keyboard shortcut (F9)) is provided for such
situations. When you invoke it, TextMaker updates all the calculations and fields in
the document.
Note: It is only necessary to use this command in the situations described above
when you want to update the screen display of the calculations. Before printing a
document, TextMaker updates all calculations and fields automatically. Text-
Maker ensures that you will never print a document with results that are out of
date.
