standard XI function inside udf

[Former Member]

The requirement is like i want to take 5 digits after decimal point. But I have to do this as part of udf.

Here I am trying to use standard XI function inside udf.

Here is my code:

com.sap.aii.mappingtool.flib3.Arithm;

double conv1=0.0;

double Input=0.123456789;

Arithm ar = new Arithm()

conv1=ar.FormatNum();

Where I have to mention the property(like 0.00000) here?

You have to set parameters in the container:

Arithm ar = new Arithm();
String input = "1.23456789";
container.setParameter("nformat","0.00000");
container.setParameter("separator",".");
String output = ar.formatNumber(input,container);

Note that all functions of the graphical mapping tool work on String.

The formatNumber uses the standard class java.text.DecimalFormat.

You might use that class directly.

Don't really understand about standard XI function inside udf

Anyway UDF is a piece of java code. You can use any java classes.

for your requirement, why not just convert the number into string and take the first 5 characters after the char '.' and then convert the result string into number?

Hi,

in this case they have to be set in the container parameters.

It's explained here:
