计算400的两个平方根

这是一个简单的程序，用于计算给定数字的平方根。我们将使用Python作为示例编程语言来实现算法。

算法

我们将使用二分查找算法来确定给定数字的平方根。该算法中，我们从数字的一半开始，逐渐逼近其平方根。我们将使用epsilon变量来指定数字和平方根之间的误差水平。

代码：

def square_root(number, epsilon):
    """Return the square root of the given number with the specified degree of precision."""
    low = 0.0
    high = max(1.0, number)
    guess = (low + high) / 2.0
    while abs(guess ** 2 - number) > epsilon:
        if guess ** 2 < number:
            low = guess
        else:
            high = guess
        guess = (low + high) / 2.0
    return guess

number = 400
epsilon = 0.01

root1 = square_root(number, epsilon)
root2 = -1 * root1

print(f"The square roots of {number} are {root1:.2f} and {root2:.2f}")
