Given a well-formed digit string " MATH<br />

Therefore, using/under the aforementioned notation and assumptions and specifications, usage of this word in " MATH<br />

Importantly, usage of this word generates an interval, not a specific number (even if such would be elliptical or vague) - meaning, among other things, that equality to such an expression would be set equality, and not numeric equality. Note that the interval which is generated excludes both endpoints but includes the center (which is the number specified by the string with this word ignored in/removed from it). As an example, where "M" represents this word: "2M000" yields (1000, 3000); meanwhile, "20M00" yields (1900, 2100); also, "19M69" yields (1869, 2069); likewise, "1.2M3" yields (1.13, 1.33). This word/function is useful for dates (example: "the mid-2000s" or "the period of two centuries which is centered on the year 1900"), ages (example: "they are in their mid-twenties", "they are older teens or young adults (fifteen to twenty-five years of age)", or "they are in their middle adult years (thirties or forties)"), or any estimate wherein the midpoint/expected value/average is known. The interval which is generated is a complete (math jargon) subset of the real numbers - there are no gaps and, in particular, the interval is not discrete (for example: it is not restricted to only the integers). Note that this word does not yield an interval of an arbitrary radius; use "[[mi'i|mi'i]]" for that. Use a construct similar to "there exists a <span class="MATH"><i>t</i></span> in (the interval) [[re|re]] [[mu|mu]] mi'i'au such that their age is measured to be (approximately) <span class="MATH"><i>t</i></span> in years" in order to express "they are in their mid-twenties (approximately 24 years old to 26 years old)"; the full English expression is wordy, but Lojban can make it concise in translation. See also: "[[mi'i|mi'i]]", "[[bi'oi'au|bi'oi'au]]", "[[su'ai|su'ai]]". (Footnote #1: this entire commentary section assumes that the method of interpretation is via a big-endian, traditional, unbalanced, positional, base-<span class="MATH"><i>b</i></span> numerical-representation system with <span class="MATH"><i>b</i></span> being an integer such that <span class="MATH"><i>b</i> &gt; 1</span>; however, the method of interpretation can be extended to other systems, such as <span class="MATH"><i>p</i></span>-adics or such as balanced integer or complex base-<span class="MATH"><i>b</i></span> systems, in natural and fairly self-evident ways, although no endeavor shall be made herein in order to do so and the assumptions about <span class="MATH"><i>b</i></span> and the method of interpretation should be as aforementioned, ignoring such possibilities for extension).<br />
