我的项目使用的是angular-cil 9.0

自己写了个求和函数,得到最终和,这个和恰好是整数,但要求要有两位小数,我这样实现得:

 {  {totle2 |  number:'0.2-2'}} 

0.2 整数位保留最小位数.小数位保留最小位数,

-2 -小数位最大保留位置
官方解释:
使用方法:number_expression | number[:digitInfo];

digitInfo是如下个格式:{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits};

minIntegerDigits:要使用的最小数字的整数位数。默认为1;

minFractionDigits:小数点后的最小位数。默认为0;

maxFractionDigits:小数点后的最大位数。默认为3;

注意:

angularjs的number过滤器使用方法:{
{ num | number : 2 }},两者不要搞混了
