FICO® Blaze Advisor® HOW-TO Discussion

Hi,

Suppose transactionAmount is a defined as a BigDecimal in the JAVA OM, how to initialize it and give it a default value.

Following code gives the error as shown below.

transactionAmount = 100.00;

Error: Explicit cast required to assign a 'real' to a 'BigDecimal' use 'as a BigDecimal'.

Kindly advise.

Thanks

the error is telling you the solution.

transactionAmount = 100.00 as a BigDecimal.

does this give you an error?

Thanks for your reply.

I have tried that as well. It complies fine but when I print the value out, the value is not passed correctly. 

Code

print("transactionAmount":transactionAmount).

Output

transactionAmount:bigdecimal#1

I am guessing that because BigDecimal is a class, I may need a different type of declaration and assignmet.

Thanks

What you see is the default representation of an object instance in Blaze Advisor. A BigDecimal instance is (at least in your case) not treated as a primitive, and is therefore represented by the instance "id" in Blaze.

If you would like to print the value represented by the BigDecimal instance, try one of the following: ("theValue" contains a reference to a BigDecimal instance)

For monetary values:

asMoney is some money initially theValue as a money;

print("value: " asMoney);

For decimal values (and you are not concerned about the possible loss of precision):

asReal is some real initially theValue as a real;

print("value: " asReal);

For integer values (still not concerned about precision etc..):

asInteger is some integer initially theValue as an integer;

print("value: " asInteger);

Please note that you can do the cast inside the print(), it is separated here for readability. Also please note that I didn't test these lines of code right now, but they should work.
