Re: %DEC

From the manual: 'When the first parameter is a numeric or character
expression, the result has precision digits and decimal places decimal
positions.' So your expression is evaluated and the result is put into a
variable with 10 digits and 2 decimal places. If you specify 5 digits and
you have a result that is greater than 999.99 you will get an error.

Hi,

In this expression :

MyProc ( MyField * MyCoefficient );

MyField is 10S 0, MyCoefficient is 2S 1 and the prototype for MyProcis
31S 9.

MyProc will output all decimal places eg 543.748000000. I need to
round down to two decimal places, eg 543.740000000.

I tried this, which works :

MyProc ( %DEC ( MyField * MyCoefficient : 10 : 2 ));

My problem is, I don't fully understand what is meant by the
precision parameter. I just tried 10 when 5 made the program crash.
