Fighting with decimals.

Former Member — Fri, 25 Nov 2005 01:55:54 GMT

I'm doing something like

DATA var1 TYPE p DECIMALS 2.

var1 = 364 / 365.

I expect to receive "0.99" but instead of I receive "1.00".

Can someone explain me a little, of how to work with decimals in ABAP?

Thanx in advance.

I looks to be rounding to the nearest, if you need to be more precise, extend the decimal places.



report zrich_0001.

DATA var1 TYPE p DECIMALS <b>3</b>.


var1 = 364 / 365.

write:/ var1.

Here you will get .997

If you need it to be 2 decimals places, then you can do something like this. There must be a better way, I can't seem to give you one at the moment.



report zrich_0001.

DATA var1 TYPE p DECIMALS 3.
data: xvar1(10) type c.
data: xvar2 type p decimals 2.


var1 = 364 / 365.

write var1 to xvar1.
shift xvar1 right deleting trailing space.
shift xvar1 right by 1 places.

xvar2 = xvar1.

write:/ xvar2.

The system will always want to round up. If you values where just a little different, of course it would show the decimal.



report zrich_0001.

DATA var1 TYPE p DECIMALS 2.

var1 = <b>360</b> / 365.

write:/ var1. " VALUE is .99

If you find these answers a little helpful, please award points accordingly, Thanks.

If you always want to round down the divsion, here is a better way. Not sure what I was thinking, maybe too much Thanksgiving Turkey.



report zrich_0001.

DATA var1 TYPE p DECIMALS 2.

var1 = ( floor( ( 364 / 365 ) * 100 ) ) / 100.

WRITE:/ var1.

Here we are doing the division, multpling by 100 for the decimal places(value now is 99.7) then round down using FLOOR(value now is 99.0, then dividing by 100 for the 2 decimals places(value now is .99
