        // value 数值
        // amount 分配数量
        // point 小数点位数
        function average(value,amount,point){
            if(!point){
                point = 2
            }
            let list  = []
            let first = (Math.floor((value/amount)*Math.pow(10,point))/Math.pow(10,point)).toFixed(point)
            let last  = (value - first*(amount - 1)).toFixed(point)
            for(let i = 0;i<amount-1;i++){
                list.push(first)
            }
            list.push(last)
            return list
        }
