Gematriya/Gematria, or perhaps more accurately, Hebrew numerals, is a system of writing numbers as Hebrew letters. This JavaScript module allows for easy conversion between gematriya and JavaScript Number types.
This code was originally written for hebcal/hebcal-js.
Install gematriya from NPM, bower, or just take the gematriya.js script from this repo.
npm install gematriya
bower install gematriya
On the client side, the API is available through the global function gematriya. In Node, require('gematriya').
A single function is available. Pass it a Number or String. Given a number, it will return the string representation. Given a gematriya string, it will return the number it represents.
When passing a string, by default, it just adds up the numbers, regardless of place. By passing {order: true} as a second parameter, it will treat it as being ordered, as per the output (see below).
When passing a number, an optional options object is available as a second parameter. Setting a number as a value for the limit key will limit the length of the returned string to a number of digits. Setting false as the value for the punctuate key will remove double and single quotation marks in the returned string. Setting geresh to false will use ASCII single/double quotes instead of Hebrew geresh/gershayim Unicode characters. Like this:
gematriya(5774) // התשע״ד - ordinary
gematriya(5774, {limit: 3}) // תשע״ד - cropped to 774
gematriya(5774, {limit: 7}) // התשע״ד - kept at 5774
gematriya(5774, {punctuate: false}) // 'התשעד' - removed quotation marks
gematriya(5774, {punctuate: true}) // 'התשע״ד' - with quotation marks
gematriya(5774, {geresh: false}) // 'התשע"ד' - with quotation marks
gematriya(5774, {punctuate: false, limit: 3}) // 'תשעד' - options can be combined
gematriya(3) // 'ג׳' - note the geresh is RTL
gematriya(3, {geresh: false}) // - "ג'" - the apostrophe is not
gematriya('התשעד', {order: true}) // 5774 - treats the characters as an ordered number
gematriya('התשעד', {order: false}) // 779 - Adds up all the characters
