ordered interval — non-logical interval connective: ordered from ... to ... --
    • Keywords: from ... to

 

Examples of bi'o Usage

Proposed Definition of mi'i

 

mi'i (BIhI)
center-range — non-logical interval connective: ordered components: ... center, ... range surrounding center --
    • Keywords:

 

Examples of mi'i Usage

le bamjakne ba darxi la moskov. mi'i lo ki'otre be li panono

le teilr. zei sujypoi pe lo dugri fancu cu jbize'a ve'a li pa ga'omi'i pa

The Taylor series of the logarithm function converges within 1 of 1, closed at the center.

Proposed Definition of ga'o

 

ga'o (GAhO)
Inclusive interval. When used before bi'o or bi'i, it indicates that the beginning of the interval is closed. When used after bi'o or bi'i, it indicates that the end of the interval is closed. When used before mi'i, it indicates that the center of the interval is closed. When used after mi'i, it indicates that the outside of the interval is closed.
    • Keywords:

 

Examples of ga'o Usage

 

Proposed Definition of ke'i

 

ke'i (GAhO)
exclusive interval — open interval bracket marker; modifies intervals in non-logical connectives; exclude boundaries --
    • Keywords:

 

Examples of ke'i Usage

 

Proposed grammar changes

In the PEG grammar, replace the line

joik <- SE-clause? JOI-clause NAI-clause? / interval / GAhO-clause interval GAhO-clause

with the line

joik <- SE-clause? JOI-clause NAI-clause? / interval / GAhO-clause interval / interval GAhO-clause / GAhO-clause interval GAhO-clause

A joik cannot be immediately followed by another joik, so a sequence "BIhI GAhO BIhI" cannot occur, so determining to which BIhI a GAhO belongs does not depend on the order in this line.

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.

Impact

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.
