Hi

I am iterating through a 2D structure with the JS patch. I want to identify if an item is of a number object type, and if so perform an operation on it and if it is string or any other non-number object, leave it alone.

What is the best test? Best meaning accurate and timely.

Tried a few things with Number.NaN and null to no avail.

Thanks
Alastair
