从字符串中提取后，我需要将美国单词数字转换为数字。我在这里尝试了一下http://jsfiddle.net/golupant/fT2tk/
即我想将 10440 转换为它的等值数字——10440。
function word2numberConverter ( wordNumber) {
wordNumber = wordNumber.toLowerCase();
//different notations under hundred
var underTen = {
'zero': 0, 'one': 1, 'two': 2, 'three': 3, 'four': 4, 'five': 5, 'six': 6, 'seven': 7, 'eight': 8, 'nine': 9
};
var underHundred = {
'ten': 10, 'eleven': 11, 'twelve': 12, 'thirteen': 13,
'fourteen': 14, 'fifteen': 15, 'sixteen': 16, 'seventeen': 17, 'eighteen': 18, 'nineteen': 19, 'twenty': 20,
'thirty': 30, 'forty': 40, 'fifty': 50, 'sixty': 60, 'seventy': 70, 'eighty': 80, 'ninety': 90
};
//different magnitude each after the increament 10 pow 3
var magnitude = {
'thousand': '10^3', 'million':'10^6', 'billion':'10^9', 'trillion':'10^12', 'quadrillion':'10^15',

http://jsfiddle.net/golupant/LFrm7/12/ - 如果数字下降的话，效果很好。意味着最高的幅度首先出现然后更小......
在http://jsfiddle.net/golupant/fT2tk/ 我试图照顾像这样的数字
“二亿五百万四百亿一千七百五十”
我一直在工作，直到一些现存但不完全正确。我只想像谷歌那样做。
请做谷歌“2.5亿401755-1”。你会知道我想要什么。
有人可以帮我做这件事吗？虽然我想要使用 javascript，但我也可以使用其他语言。
