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 true as a second parameter, it will treat it as being ordered, as per the output (see below).
When passing a number, a second parameter is available, limit. This will limit the length of the returned string to a number of digits. For example:
gematriya(5774) // התשע"ד - ordinary
gematriya(5774, 3) // תשע"ד - cropped to 774
gematriya(5774, 7) // התשע"ד - kept at 5774Licensed MIT.
