Hi,

I would like to truncate the value after doing a calculation, but the value should not round up.

For example, after calculation the result comes to 100.4586508
I want the value to be 100.45 only. Normally the value would get rounded up to 100.46.

How do I do this?

Thanks
Ramesh

Ramesh,

If you are talking about COBOL, Here is the solution

Declare variable like
01 WS-C PIC 9(03).99

Use ADD Verb without ROUND option

like ADD WS-A WS-B giving WS-C

Vasanth,

Lets assume, i have value

in WS-A = 50.00
WS-B = 50.4586508 <assume PIC 9(2).9(7)>

On execution of above ADD VERB, The WS-C will have value 100.45 because WS-C is declared as 9(02).99

Suppose if You are using ADD VERB with ROUNDED option like

ADD WS-A WS-B GIVING WS-C ROUNDED

Then the result will rounded to you

Hi Raghu,

In this case, the value would come as 100.46 only, but I want the value to be with 100.45.

Results of Arthimetic calculations in COBOL will get rounded provided if u code verb ROUNDED.

If you are not coding verb ROUNDED, it will not rounded up.

or, after the calculation, you can simply move it to a field defined with only 2 decimal positions.

Ramesh,
Move the result you are getting after calculation to a variable of PIC clause 9(2)V99.
