gives full and approximate written forms of numbers
Project description
A pure Python module that gives both full and approximate names for numbers
Contains functions that give the cardinal name (one, two, three, …), the ordinal name (first, second, third, …) as well as approximations (23.3458e45 -> ‘23.346 quattuordecillion’). Has four different naming methods for powers and three different suffix styles.
Suffix Styles
short - Assigns ‘illion’ to names. This is the default style.
10^6 = million, 10^9 = billion, 10^12 = trillion, …
long - Assigns ‘illion’ or ‘illiard’ to names depending on power.
10^6 = million, 10^9 = milliard, 10^12 = billion, …
british - Assigns ‘illion’ and adds ‘thousand’ in front of names depending on power.
10^6 = million, 10^9 = thousand million, 10^12 = billion, …
Naming Methods
conway-wechsler - This system extends the normal Latin naming method indefinitely and follows Latin syntax closely. Can use long, short or British suffix styles (examples below are short style). This is the default method.
10^6 = 1 million
10^12 = 1 trillion
10^51 = 1 sedecillion
10^342 = 1 tredecicentillion
noll - This system extends the normal Latin naming method indefinitely. Can use long, short or British suffix styles (examples below are short style).
10^6 = 1 million
10^12 = 1 trillion
10^51 = 1 sexdecillion
10^342 = 1 centredecillion
rowlett - This system uses Greek prefixes for names. Introduced to prevent confusion the suffix styles can cause and therefore does not use any such styles. Currently valid up to 10^2999.
10^6 = 1 million
10^12 = 1 gillion
10^51 = 1 heptadekillion
10^342 = 1 hecatodekatetrillion
knuth - Radically different naming method introduced to prevent confusion the suffix styles can cause and thus does not use any styles. Inherits conway-wechsler system to extend naming scheme indefinitely (original paper stopped at 10^4194304).
10^6 = 100 myriad
10^12 = 10 myllion
10^51 = 1000 byllion tryllion
10^342 = 100 myriad byllion quadryllion sextyllion
