Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
num-tofixed
Advanced tools
npm install num-tofixed --save
测试用例
npm install
npm test
示例:
// 通过script标签引入
// var toFixed = window.toFixed;
var toFixed = require('num-tofixed');
// 精确度取四舍五入值
toFixed(0.099999,3,true) // '0.100'
toFixed(0.999999,3,true) // '1.000'
toFixed(0.09,2,true) // '0.09'
toFixed(0.09,1,true) // '0.1'
toFixed(0.09,5,true) // '0.09000'
toFixed(0.09,0,true) // '0'
toFixed(0.99,3,true) // '0.990'
toFixed(0.99,1,true) // '1.0'
toFixed(.99,3,true) // '0.990'
toFixed(1.099999,3,true) // '1.100'
toFixed(1.999999,3,true) // '2.000'
toFixed(1.09,2,true) // '1.09'
toFixed(1.09,1,true) // '1.1'
toFixed(1.09,5,true) // '1.09000'
toFixed(9.09,0,true) // '9'
toFixed(9.99,3,true) // '9.990'
toFixed(9.99,1,true) // '10.0'
toFixed(199.9999,3,true) // '200.000'
// 根据精确度直接截取小数点
toFixed(0.099999,3,false) // '0.099'
toFixed(0.09,2,false) // '0.09'
toFixed(0.09,1,false) // '0.0'
toFixed(0.09,5,false) // '0.09000'
toFixed(0.09,0,false) // '0'
toFixed(0.99,3,false) // '0.990'
toFixed(.99,3,false) // '0.990'
说明: 修正原生toFixed方法的精度问题,支持四舍五入和直接截取
num: String|Number
, 需要取精度的数字或则可转换为数字的字符串
digit: Number
保留的小数点位数,可取范围为(0,20],末尾不足位数时补0
isRound:Boolean
保留小数点时是否进行四舍五入,默认为false,即直接截取,不进行四舍五入
return String
