字符串转成数字的多种方式
如下
typeof Number('44.5');
typeof parseInt('44.5');
typeof parseFloat('44.5');
typeof ('44.5'-0);
typeof +'44.5';
typeof ('44.5'*1);
typeof ~~'44.5';//http://james.padolsey.com/javascript/double-bitwise-not/
typeof '44.5'|0
还有其它的吗？

If you cannot hear the sound of the genuine in you, you will all of your life spend your days on the ends of strings that somebody else pulls.
