From Lojban to English :
Word: xaudbo [jbovlaste]
Type: fu'ivla
Gloss Word: half order of magnitude in the sense of "decimal, multiplicative order; SI prefix"
Gloss Word: half-order SI prefix
Gloss Word: sqrt 10 in the sense of "SI prefix"
Definition: x1 is $\sqrtA = \sqrt2*5$ [decimal: $1\times10^+(1/2)$]
of x2 in dimension/aspect x3 (default is units).
Notes: This works as all other Metric prefixes do. In decimal,
$10^(1/2)=\sqrt(10)=3.16227766\dots$ (also
expressed/represented in decimal). In different bases, this
value may change; for example, in hexadecimal, it might be
exactly four ($4$); however, this is an outstanding as-of-yet
unsolidified area in the Lojban grammar/semantics (do "ki'o"
and Metric prefixes change according to the base?). This number
is nice, as it is close to both 3 and and the circle constant
pi ($\pi$) in decimal usage; these three values arise fairly
frequently and a great trick in decimal Fermi estimation is to
use their approximate identity in order to simplify
expressions. Now, when the quantity is dimensionful (has
units), if the mantissa approximates this value, then one can
instead express the mantissa as approximately 1 and the unit as
being augmented by this prefix. This word is also good for
short-hand/quick expressions. This word has no English
equivalent and is not part of the official set of SI prefixes,
but it does generalize them. "xaudbo" = "kamre li dau
te'a fi'u re" in decimal (if it generalizes for other
bases, change "dau" into the base; in other words, "dau"
generally becomes "pano" in such case, where the base is given
by context). While this suggestion is not perfectly compatible
with SI (which allows only one prefix at a time), the
negative-power version of this ("kamre li dau te'a ni'u fi'u
re", where "dau" has the aforementioned caveats;
$1\times10^-(1/2)$) can just be expressed as a
lujvo/rafsi/tanru containing both "decti" and this word (as
veljvo/selrafsi/seljavytertau), because
$A^(-1/2)=\sqrt(1/A)=A^(+1/2)/A$, and $A$ (ten in at
least decimal) is the base. A "xaudbydectre" is a single unit
which (in decimal) happens to approximate an imperial/U.S.
customary foot (unit). See also:
