Problem Statement

Write a function which tests if infinity is supported for floating point numbers (this step should be omitted for languages where the language specification already demands the existence of infinity, e.g. by demanding IEEE numbers), and if so, returns positive infinity.   Otherwise, return the largest possible positive floating point number. For languages with several floating point types, use the type of the literal constant   1.5   as floating point type.

Let's start with the solution:

def biggest = { Double.POSITIVE_INFINITY }


println biggest()
printf ( "0x%xL \n", Double.doubleToLongBits(biggest()) )
