WordToNum (js)

Convert a string containing word-numbers to all their digits

WordToNum lets you normalize any string for all of its word-numbers into digits, as well as extract word-numbers into an array of numbers. Ordinal numbers ("first, second, third") are normalized to cardinal numbers ("1, 2, 3").

"eleventh floor"
- normalize: "11 floor"
- extract: [ 11 ]
"Show me number two hundred"
- normalize: "Show me number 200"
- extract: [ 200 ]
"twelve cards and two dices"
- normalize: "12 cards and 2 dices"
- extract: [ 12, 2 ]
"it's minus seven point five degrees"
- normalize: "it's -7.5 degrees"
- extract: [ -7.5 ]

Usage

There are two main functions, one to normalize text, one to extract numbers.

var WordToNum = require( "word-to-num.js" );
var w2n = new WordToNum();

w2n.normalize( "eleventh floor" ); // "11 floor"
w2n.extract(   "eleventh floor" ); // [ 11 ]
w2n.normalize( "Show me number two hundred" ); // "Show me number 200"
w2n.extract(   "Show me number two hundred" ); // [ 200 ]
w2n.normalize( "I want the second one" ); // "I want the 2"
w2n.extract(   "I want the second one" ); // [ 2 ]
w2n.normalize( "twelve cards and two dices" ); // "12 cards and 2 dices"
w2n.extract(   "twelve cards and two dices" ); // [ 12, 2 ]
