在bash脚本中获取溢出以计算多项式系数

#!/bin/bash

# 输入多项式的阶数
read -p "请输入多项式的阶数: " n

# 初始化系数数组
coefficients=()

# 循环读取系数
for ((i=0; i<=n; i++))
do
    read -p "请输入第 $i 个系数: " coefficient
    coefficients+=($coefficient)
done

# 计算多项式的值
result=0
for ((i=0; i<=n; i++))
do
    power=$((n-i))
    term=$(echo "scale=10; ${coefficients[$i]} * (x^$power)" | bc)
    result=$(echo "scale=10; $result + $term" | bc)
done

echo "多项式的值为: $result"
