CREATE EXTENSION numeral;Usage
The numeral extension provides three custom numeric data types that use textual numerals instead of digits.
CREATE EXTENSION numeral;Data Types
numeral: English numerals using short scale (10^9 = billion)zahl: German numerals using long scale (10^9 = Milliarde)roman: Roman numerals
All three are internally binary-compatible with bigint and implicitly cast to it.
Examples
-- English numerals
SELECT 'thirty'::numeral + 'twelve'::numeral;
-- forty-two
-- German numerals
SELECT 'siebzehn'::zahl * 'dreiundzwanzig'::zahl;
-- dreihunderteinundneunzig
-- Roman numerals
SELECT 'MCMLV'::roman + 'II'::roman * 'XXX'::roman;
-- MMXVOperators
Standard arithmetic operators (+, -, *, /) work through the implicit bigint cast. All existing bigint operators and functions are available.
