double a1=157;
double a2=32;
int total = (int) Math.ceil(a1/a2)
Math.ceil is not the same as rounding ...

java should be fine.

Although I am using a different  language   but  java  should get this thing done there.  I am using a BPM tool where language similar to java is used.

Here is the actual language  though http://openl-tablets.sourceforge.net/

I am stuck to do this two things  basically :

Isssue 1 :

Double d1
Double d2

Double d3 = (d1/d2)*100  // round up this  result upto 3 digits

Issue 2:

Double d1
Double d2

Double d3 = (d1/d2)*100  // round up the  result to integer

I am looking for a  solution .   provide  me few choices to try with.  Need help at this part.

Rounding is done in Java at presentation time, since there is usually no reason to diminish accuracy until then

String presentationValue = String.format("%.3f", d1/d2*100);

String presentationValueAsInteger = String.format("%d", Math.round(d1/d2*100));

Thanks CHEJ,

I would love to use that ...

But String format is not recognized in this language  http://openl-tablets.sourceforge.net/  

Is there any mathematical solution ?  without  any API method call
I don't know the language, so i'm giving you Java, as you asked ;)
Try NumberFormat
