本版中只有一个用于生产环境的文件：BigDecimal-all-last.min.js，大小为26K,如果WEB服务器打开GZIP压缩，可以减小至7K，如需完整版本请移步至：http://download.csdn.net/detail/aquaqu2009/4575230 简单用法： var scale = 20; var e = new BigDecimal("0"); var denominator = new BigDecimal("1"); var eBefore = new BigDecimal("-1"); var iteration = 1; while (!e.equals(eBefore)) { eBefore = e; e = e.add(BigDecimal.prototype.ONE.divide(denominator, scale, BigDecimal.prototype.ROUND_HALF_UP)); denominator = denominator.multiply(new BigDecimal(iteration+'')); ++iteration; } equal(e.toString(), "2.71828182845904523536"); ok(new BigDecimal("1234.5678").isPositive(), "1234.5678 is positive"); ok(new BigDecimal("-1234.5678").isNegative(), "-1234.5678 is negative"); ok(!BigDecimal.prototype.ZERO.isPositive() && !BigDecimal.prototype.ZERO.isNegative(), "BigDecimal.prototype.ZERO is neither positive nor negative"); ok(BigDecimal.prototype.ZERO.isZero(), "BigDecimal.prototype.ZERO is zero"); ok(new BigDecimal("1234.0000").isLessThan(new BigDecimal("1234.5678")) && new BigDecimal("1234.0000").isLessThanOrEqualTo(new BigDecimal("1234.5678")), "1234.0000 is less than 1234.5678"); ok(!new BigDecimal("1234.0000").isGreaterThan(new BigDecimal("1234.5678")) && !new BigDecimal("1234.0000").isGreaterThanOrEqualTo(new BigDecimal("1234.5678")), "1234.0000 is not greater than 1234.5678"); ok(new BigDecimal("1234.5678").isGreaterThan(new BigDecimal("1234.0000")) && new BigDecimal("1234.5678").isGreaterThanOrEqualTo(new BigDecimal("1234.0000")), "1234.5678 is greater than 1234.0000"); ok(!new BigDecimal("1234.5678").isLessThan(new BigDecimal("1234.0000")) && !new BigDecimal("1234.5678").isLessThanOrEqualTo(new BigDecimal("1234.0000")), "1234.5678 is not less than 1234.0000"); ok(new BigDecimal("1234.5678").isLessThanOrEqualTo(new BigDecimal("1234.5678")) && new BigDecimal("1234.5678").isGreaterThanOrEqualTo(new BigDecimal("1234.5678")), "1234.5678 is less than or equal to itself as well as greater than or equal to itself"); 别整个复制粘贴啊，那样是运行不起来的，请粘贴您需要的代码，，
