回到顶部(go to top) 最大安全整数 从以上表示公式我们能看到,当指数部分只取 1 位,尾数部分取满 52 位时,可以精确表示出 JavaScript 里的整数,其 16 进制形式为0x001f_ffff_ffff_ffff,即9007199254740991。 它等于 2 的 53 次方减 1,在 ES6 中,可以通过Number.MAX_SAFE_INTEGER引用到这个数值。
如果格式化字符串中包含单引号,处理方法是用2个单引号进行转义: String responseTemplate = "'{'code:''{0}'',des:''{1}'''}'"; System.out.println(MessageFormat.format(responseTemplate, "w1","w2")); 处理结果:{code:'w1',des:'w2'}
