Lojban/Numbers

The numbers zero to nine in Lojban:


  • 0=no
  • 1=pa
  • 2=re
  • 3=ci
  • 4=vo
  • 5=mu
  • 6=xa
  • 7=ze
  • 8=bi
  • 9=so


The hexadecimal numbers from A to F:


  • A=dau
  • B=fei
  • C=gai
  • D=jau
  • E=rei
  • F=vai


Larger numbers are constructed by combining these digits: pano is 10, vore is 42, binoso is 809, and so on.


Numbers 1,000 and onward may have a comma or period in them. This too is represented in Lojban, as ki'o. Thus 7,530 is ze ki'o mucino. ki'o can also let the speaker omit unnecessary numbers: if all the digits after ki'o are zero, then they do not need to be included. So one could say panonono (1,000) but it would be easier to say pa ki'o, which means the same thing.


Decimals are handled with pi, which is quite simply a decimal point in the form of a word. cipivo is 3.4, sopixa is 9.6, etc.

  • pi is actually a unit point. Therefore, if one is working with the hexadecimal system when pi is used, it is a hexadecimal point.


The number pi (about: 3.14159), is expressed in Lojban as pai.


To use numbers as sumti, the article li is used. So li muvozeci is "the number 5,473." To say more than one number without them combining to one number, insert li before each one. so bi ze is 987, whereas li so li bi li ze is "nine, eight, seven."
