Numbers in Katian

Cardinal numbers
Cardinal numbers denote given amounts and measurements. In Katian, these are the fundamental ones:
 * also refered to as zén in colloquial speech. This change affects the whole line from 10 to 19

If a number is in the range 21 to 99, and the second digit is not zero, one writes the number as two words separated by a hyphen, as we see in numbers like 13 or 17 above. In Katian, hundreds are formed by using the number of hundreds with the suffix ''-piendi. It is important to note that the word piendi on its own can also be used to say one hundred'', in colloquial speech. So too are the thousands, with the number of thousands followed by the suffix síení. It is important to note that the word síení on its own can also be used to say one thousand, in colloquial speech. Before going into more detail about millions, billions, etc, it is important to note that Katian language always uses the short scale. I.e. the number after 999.999.999 is called a billion, not a thousand million.

Ordinal numbers
Ordinal numbers refer to order or position in a series. They are formed just by adding the ending "bien" at the end of the number. It is important to add that, when we write numbers in digits, this "bien" ending takes the form of an "n." after the number.

The formation of ordinals with composed numbers works exactly the same way:

Fractions and decimals
Fractions (the denominators) are formed by using a number and adding the ending kei (which means part, section, division). When pluralized, this ending becomes keisí. As far as decimals are concerned, Katian can only bild these with commas (never periods). In pronunciation, one says the word "fegy" (comma) before saying the decimals.
