Hm, actually, something weirder is going on:
isNaN('1.5x') -> true
isNaN('1.5d') -> false
What is it about "d"? Is it some kind of numerical literal? Again, this
is not standard behavior for JavaScript.

In most JavaScript engines, this would return true if value is fully
numerical:
!isNaN(value - 0)
But in Nashorn, it returns true if even if value is a string that
begins with a number. It seems that arithmetic with strings is working
non-standardly in Nashorn.
