Description

In BBj 7.0 and higher, the BBjNumber object defines an object-oriented interface to traditional BBx numbers. It is not a java.lang.Number, but it implements the conversion methods defined by that class. This API is primarily designed to facilitate interaction with Java libraries.

Creation

All numeric values created in BBj are BBjNumbers. To access BBjNumber methods, copy a BBj numeric value to an object variable:

number! = num("1")
print number!.booleanValue()
