var result = parseFloat(numStr).toFixed(digit); console.log(result); // 输出结果为:123.46 ``` 需要注意的是,使用 toFixed() 方法时,最终返回的是字符串类型,而不能进行数学运算;而使用 parseFloat() 方法时,需要先将字符串解析成浮点数后才能进行数学运算。 除此之外,还可以使用第三方库,如 Decimal....

Although dec is an optional property, it is highly recommended that the number of decimals is specified: otherwise, all unneeded trailing zeros will be removed and computed values could be shown with more decimals than the original values. Default value can be set in visual.setup.js. type St...

Math.round(number)必选项 number 参数是要舍入到最接近整数的值。说明 如果 number 的小数部分大于等于 0.5，返回值是大于 number 的最小整数。否则，round 返回小于等于 number 的最大整数。而你的写法, 根本就没有用, 没有这样的写法 你自己创建一个方法 function xround(x, num){ Math.round...
