NCL bug

I have found a bug in NCL version 5.1.1, although a colleague of mine
confirmed that the same error in NCL version 6.0.0.

If I create an array (called "x") that contains increments from 0 to 1
by 0.01, I run into problems when x should equal 0.9. The print()
function says that x(90) = 0.9, yet x(90) > 0.9 after some
investigation. This only seems to be occurring at x = 0.9. Why is this
the case?

I have attached a simple script to view this error.

Thank you,
Gus Alaka
