JavaScript语言实现类似这样的效果: 3.grams.flour 参考 Javascript: The Good Parts，第33页代码如下:<html><body><script type="text/javascript">// copied from page 33 of Javascript: The Good PartsFunction.prototype.method = function (name, func){ this.prototype[name] = func; return this;}Number.method(‘chi’, function() { return this*0.333;});document.writeln( (3).chi());document.writeln( "<br>" );document.writeln( (3+1).chi() );document.writeln( "<br>" );document.writeln( 3.2.chi() );document.writeln( "<br>" );document.writeln( 3.0.chi() );// document.writeln( 3.chi() );// SyntaxError: identifier starts immediately after numeric literal</script></body></html>运行结果如下:0.99900000000000011.3321.0656
0.9990000000000001
努力学习，苦中作乐。
，继续期待我的下一个旅行，拿起背包，
