Decimal Calculation Problem

Former Member — Tue, 30 Jun 2015 09:59:28 GMT

Hi All,

I am a newbie of ABAP programming. I have create a new routine for condition value by VOFM.

FORM FRM_KONDI_WERT_908.

*{ INSERT

DATA: p_value(7) TYPE p DECIMALS 4.

p_value = komp-brtwr * konp-kbetr / 10000.

xkomv-kbetr = konp-kbetr / 10.

xkwert = p_value.

*} INSERT

ENDFORM.

It is very strange that if p_value = 1.2340, xkwert will equal to 123.40 but not 1.23. It seems like the number format is right-justified.

Please kindly help on this issue....I have hold on this for a few days...Thanks~~!!

Hi Chan,

what value you are getting at the run time in xkwert ?

as per the data declaration by you , the result of xkwert shouldbe 1.23 itself.

Regards,

Sujatha Arsid.

This is because "Fixed point arithmetic" checkbox is not checked for the main program SAPLV61A.

For this reason, it is always better to declare your own function group, and function module inside it, with the required calculation and just call the function module from the routine. Don't do calculations directly inside the routine.

Thanks,

Juwin

Hi Ka Wai Chan,

I second Juwin.. He is right. SAPLV61A does not hv Fixed Point Arithmetic checked. Create a FM with Fixed Point Arithmetic checked (Attribute menu)

Take a look of a example of FM with Fixed Point Arithmetic checked and unchecked.

1. Both Program and FM with Fixed Point Arithmetic UNCHECKED.

Expect output is 1.235, but 12.35 is wrongly displayed.

2. Program with Fixed Point Arithmetic UNCHECKED and FM with Fixed Point Arithmetic CHECKED (exact your scenario). Output is 1.24
