Incorrect explanation of the value returned by dyadic iota when no element is found about learnapl HOT 2 CLOSED

Similarly, in the explanation of Interval Index:

Similarly, elements greater than the last bin will end up with a bin number equal to the number of elements (note: not the number of bins) to the left:

And the following example is given:

      3 5 7 9⍸0 100
┌→───┐
│¯1 3│
└~───┘

There are 4 elements on the left side of ⍸ and for 100 it returns 3, not 4. If we set ⎕IO to 1 on the other hand, the explanation is correct (for 100, but not for 0, which now gets 0 instead of -1):

      ⎕IO ← 1
      3 5 7 9⍸0 100
┌→──┐
│0 4│
└~──┘

Thank you for pointing this out. I'll be sure to address this in the next update I make.
