rounding up numbers

My proposal for integer values:

VAR
    a: INT;   // Dividend
    b: INT;   // Devisor
    c: INT;   // Result
END_VAR

-----

c := (a-1)/b+1;

I needed that conversation for getting the correct number of column and row, out of the (overall) count of an array (to correct the code of OSCAT's "CSV_PARSER_FILE_DEMO"). It works with the integrated truncation feature while calculating with integer values. Or you look after "ROUND" functions in OSCAT's library.

Thank you. I tried it and it worked

So what do you want ?
If you want to be see 3/2 = 1.5
you have to define LREAL variable.

For example,

variable1 : LREAL;

variable1 := 3/2;

so, you can see variable1 = 1.5

Hi all,

Probably a stupid question but i have some troubles with rounding up numbers. So just like 3/2 = 2
It Always has to be rounded to the biggest number.
Any suggestions here? (i don't use the oscat library)

Many thanks.
