D'ni/Numbers
Note: As noted on the index of this wikibook, you will need the D'ni font to view characters correctly.
The D'ni used a base25 numeric system. This means that one symbol is used to represent each numeral from 0 through 24. In the same way that another digit is added to integers at each power of 10 in the base10 (or decimal) system the modern world uses, so does a base25 system add another of its numerals at each power of 25.
We can see similarities between the D'ni letter and number systems. Supposedly, letters were evolved from numbers as they grew more calligraphed.

The appearance of each numeral follows the logic of five: Every fifth number (i.e. 5, 10, 15, 20) is created by rotating the symbols representing 1 through 4 counterclockwise. This is done respectively; or as the table below shows, each pair of unrotated and rotated numerals are in the same position on their separate axes, and meet each other directly across a grid, such that the symbol for 5 is a rotated 1, 10 is a rotated 2, etc...
Following this concept of a grid, the remaining numerals are created by combining the standard numerals where they meet on the grid.
 e.g. By combining the numeral for 5 ( 5 ) with the numeral 2 ( 2 ), you create the numeral for 7 ( 7 ).
Pronunciation of D'ni Numerals[edit  edit source]
In D'ni, like in most languages, there exists not only a symbol to represent its numerals, but also a spoken word for each numeral. 1, 2, 3, 4, 5, 10, 15, and 20 each have their own word (see table). The names of the numerals that are created by combining those standard numerals follow the same logic of combination across the grid. The D'ni word for "and," ga, is inserted between the two standard numerals, always remembering to express the 5numeral first, then the 1, 2, 3 or 4.
 e.g. 7 is called "vagabrí," which means 'five (vat) and (ga) two (brí)'.
It is also worth mentioning that the corresponding "five," i.e. 5, 10, 15, or 20, is abbreviated when compounded with 1, 2, 3, or 4 to form the numerals of its row.
 e.g. "Híbor" (15) is abbreviated to "hí" when combined with "brí" (2) to form "hígabrí" (17).
Greater Numbers[edit  edit source]
The key to understanding how to construct numbers greater than 24 in D'ni is remembering that the D'ni numeral system is very similar to the decimal system in its basest aspects. For instance, like our decimal system, the D'ni numeral system works on a basis of place value.
Place Value[edit  edit source]
Place value refers to the location of a numeral relative to another in a number, and the inherent value of the power associated with that location by which the number is multiplied.
For example, in the decimal number 4,321, (from right to left) the 1 takes the "ones" place, the 3 takes the "tens" place, the 2 takes the "hundreds" place, and the 4 takes the "thousands" place. Mathematically, these places are expressed in powers. The "ones" place is represented by 10^{0}. (Here, it is important to remember the mathematical rule which states that anything to the 0power equals one.) The "tens" place is represented by 10^{1}, the "hundreds" place by 10^{2}, the "thousands" place by 10^{3}, etc. Thus, the underlying mathematical principal behind our example, and all decimal system numbers is as follows: (1×10^{0})+(2×10^{1})+(3×10^{2}+(4×10^{3})=4,321. Of course, since most of us grow up knowing this concept intrinsically, if not literally, we have no need of parsing it out in this way; however, it is important to understand these concepts when trying to understand a place value numeric system of a different base, such as that of D'ni.
With D'ni, it is the same basic concept, except that instead of using 10, we use 25, because it is a base25 system. Past the first 25 numerals which represent the first place value, there are only 5 other known place values The place values, from right to left, are as follows:
 The first place value is represented mathematically by 25^{0}.
 The second place value is represented mathematically by 25^{1}.
 The third place value is represented mathematically by 25^{2}.
 The fourth place value is represented mathematically by 25^{3}.
 The fifth place value is represented mathematically by 25^{4}.
 The sixth place value is represented mathematically by 25^{5}.
In this way, we can translate the D'ni numbers into a decimal system numbers, which are typically easier for us to use:
 @73 and
 1:
become
 (3×25^{0})+(7×25^{1})+(12×25^{2})=(3)+(175)+(7500)=7678 and
 (0×25^{0})+(1×25^{1})=(0)+(25)=25
Pronunciation of Greater Number Place Values[edit  edit source]
Just like how in our decimal system, we speak our place values (e.g. "four thousand three hundred twenty one"), so did the D'ni speak their place values. Remember that past the 25 numerals, there are only 5 known spoken place values.
Also note that just like in English, in D'ni, a place value that has no value, i.e. a value of 0( : or rún), is not spoken.
Simple Examples[edit  edit source]
 "sí" is the spoken form of the 25^{1} place value. So...
 25 (1x25^{1}): fasí ( 10 ) (There is a special character for 25 that can be used by itself, but it is rarely used: ; )
 50 (2x25^{1}): brísí( 20 ),
 75 (3x25^{1}): sensí ( 30 ), etc.
 "ra" is the spoken form of the 25^{2} place value. So...
 625 (1x25^{2}): fara ( 100 ),
 1250 (2x25^{2}): bríra ( 200 ),
 1875 (3x25^{2}): senra ( 300 ),
 "lan" is the spoken form of the 25^{3} place value. So...
 15,625 (1x25^{3}): falan ( 1000 ),
 31,250 (2x25^{3}): brílan ( 2000 ),
 46,875 (3x25^{3}): senlan ( 3000 ), etc.
 "mel" is the spoken form of the 25^{4} place value. So...
 390,625 (1x25^{4}): famel ( 10000 ),
 781,250 (2x25^{4}) brímel ( 20000 ),
 1,171,875 (3x25^{4}): senmel ( 30000 ), etc.
 "blo" is the spoken form of the 25^{5} place value. So...
 9,765,625 (1x25^{5}): fablo ( 100000 ),
 19,531,250 (2x25^{5}): bríblo ( 200000 ),
 29,296,875 (3x25^{5}): senblo ( 300000 ), etc.
Quantity[edit  edit source]
The numbers from 0 to 25 are used for expressions like ‘little’, ‘very’, ‘much’ etc... the larger the number, the greater the emphasis... e.g. tégan šem b’fasí ‘I love you to 25/absolutely’. To exaggerate, numbers greater than 25 are used, like 'I love you to 50!!!'
Ablative[edit  edit source]
For expressions like '[number] of the...' English as well as most languages uses the genitive. This is not the case with D'ni which uses the preposition te which has the usage of the Latin ablative.
An expression like 'one of the caves' would be 'one to the caves' (fa tregalpotí). Similarly fa terþtes is translated as 'One of a group'
Ordinals[edit  edit source]
Some special constructions exist (Kor’fa, Lísan, etc.) but ordinality is expressed by adding the 'ec' suffix to the cardinal number. Thus, ‘second rock’ is præd bríec, ‘third master’ is nava senec, etc.
