### General Section Notes

BIhI may be used with only one GAhO next to it; this indicates that one end of the interval is closed or open, but says nothing about the other end. The Taylor series mentioned above diverges at 0, but converges at all other points on the boundary of the disk of convergence; thus the outside is neither closed nor open.

The definition of GAhO with mi'i differs from that in CLL, but there appears to be no prior usage of GAhO with mi'i.

Allowing BIhI with only one GAhO is a change in the grammar. Since GAhO is used only with BIhI, and no GAhO BIhI GAhO may be followed immediately by another GAhO BIhI GAhO, this introduces no new ambiguity.

#### Interval or Point?

There is a question whether abu bi'i by denotes the interval a..b or some point in the interval. Here are some examples, showing which way it has been used:

lo kanla be lo remna cu viska loi gusni poi boxna folo navytre beli 400 bi'i li 800
"The human eye can see light of wavelength between 400 and 800 nanometers."
