有效数字

• If the rounded value contains more than 15 digits , the 15 most significant digits are returned
  如果舍入的值包含的位数大于15 ，则返回15位最高有效数字。
• Where both formats can present the same number of significant digits , fixed format is used
  当两种格式可以保留同样多的有效数字的时候，优先使用固定格式。
• The format chosen is the one which can present the greater number of significant digits
  具体选用何种格式表现则取决于究竟哪种格式能够保留更多的有效数字。
• If the year without the century is less than 10 , the year is displayed with no leading zero
  显示秒的小数部分的最高有效数字。如果该数字为零，则不显示任何内容。
• The most recent available figures show that about a quarter of a million people are incapacitated with back pain every day
  最新有效数字显示每天有25万人因背痛而致残。
• If the precision specifier is present and the number of significant digits in the result exceeds the specified precision , then the excess trailing digits are removed by rounding
  如果精度说明符存在，并且结果的有效数字位数超过指定精度，则通过舍入删除多余的尾部数字。
• Koal ssl security authentication gateway protects web servers ( such as oa server ) through certificates . only the employees who have valid certificates will be admitted to the web server
  格尔ssl安全认证网关通过使用数字证书来保护企业的web服务器（如oa服务器） ，只有具备有效数字证书的员工才能访问web服务器。
