But this system was limited: it made it awkward to talk about numbers in the abstract, and gave us no natural way to extend the system to more "exotic" numbers like the negative integers, non-integers, or even zero for that matter. | ||
There have been plenty of number system proposals in the past (particularly in the days of Toaq Beta), but now that we have prefixes to play with and special grammar for pronouns, I think Delta has given us the chance to do even better. | |||

To form larger numbers | To form larger numbers, the golden rule is "each digit is a word". The tens place is marked with {{Derani||heı}}, and the hundreds place with {{Derani||fue}}. So for example, 123 would be spoken as {{Deranize|shífue guheı saq}}. Note that we never write out {{Deranize|koam}} as a digit, and {{Derani||shıheı}} and {{Deranize|shıfue}} may be abbreviated to simply {{Derani||heı}} and {{Derani||fue}}. | ||
To form ''even larger'' numbers, put the appropriate | To form ''even larger'' numbers, keep going with {{Derani||heı}} and {{Derani||fue}}, but put the appropriate scale word ({{Deranize|bıq}}, {{Deranize|nhoeı}}, {{Derani||gıga}}, {{Derani||tera}}…) after each group of three digits. | ||
{{Example|{{Deranize|Chum bua jẹ́mshı nhoeı cıheı bıq req ní doaq.}}|About one million, fifty thousand people live in this city.}} | |||

The prefix {{Deranize| | The prefix {{Deranize|peo-}} can also form fractions: for example, {{Deranize|fé pẹocı}} is the number 5/6, and {{Deranize|shí pẹofue}} is 1%. Just as a quantity requires both a number and a unit, a fraction requires both a numerator and denominator; {{Deranize|pẹofue}} isn't particularly meaningful on its own. | ||
Fractional units are a little different from units proper, because they form numbers, not quantities. That is, in {{Deranize|róaı | Fractional units are a little different from units proper, because they form numbers, not quantities.

Quantities add together when put next to each other:{{Example|{{Deranize|Fáfuaq mı Taıtanıko bï duo hóq sáq hora heı jo mınu da.}}|The movie Titanic is 3 hours and 14 minutes long.}}You can also combine a whole number and a fraction to produce a '''mixed number'''. Just put {{Deranize|roı}} between the whole number and the fraction:{{Example|{{Deranize|Luı pıe jí shí roı shı pẹogu lıta nao.}}|I've had 1 ½ liters of water.}} | ||

Some words like {{Deranize|puı}} and {{Deranize|tıopuı}} are pseudo-numbers: they can't stand alone as a number pronoun, but can still be used with certain prefixes, such as {{Deranize|ne-}} and {{Deranize|nho-}}. | Some words like {{Deranize|puı}} and {{Deranize|tıopuı}} are pseudo-numbers: they can't stand alone as a number pronoun, but can still be used with certain prefixes, such as {{Deranize|ne-}} and {{Deranize|nho-}}. | ||

== Writing conventions == | |||
Of course, numbers are cumbersome to spell out in full, so we normally just write them with Arabic numerals. Toaq uses the dot "." as a decimal separator and the comma "," to divide groups of three digits, as in "10,000.56". | |||
One challenge when using Arabic numerals is where to put the tone marks: numbers can appear in different tones, and computers in particular have a hard time inserting and displaying diacritics on top of numbers. For this reason, we adopt the following conventions: | |||
* By default, a bare number such as 24 is assumed to be in the rising tone ({{Deranize|gúheı jo}}). | |||
* A verb of cardinality should have its {{Deranize|ne-}} prefix written out explicitly ({{Deranize|guheı jo}} → {{Deranize|nẹ24}}). | |||
* A numeric determiner in the hiatus tone {{Done|4}} should have its {{Deranize|nho-}} prefix written out ({{Deranize|kıaı gû gochıq}} → {{Deranize|kıaı nhộ2 gochıq}}). | |||
* A number pronoun in the hiatus tone {{Done|4}} should have the prefix {{Deranize|no-}} added ({{Deranize|Huaq gû sáq}} → {{Deranize|Huaq nộ2 3}}). | |||
