The round() function rounds off a floating-point number to a specified number of decimal places. Example 1: Python 1 2 3 4 # Rounding a floating-point number num = 3.5678 print(round(num, 2)) Output: Explanation: Here, round() rounds off the number to 2 decimal places. Example 2:...
3. 否则,通过平均g和x/g来创建一个新的猜测,即(g + x/g)/2。 4. 使用这个新的猜测,我们再次称之为 g,重复这个过程,直到g*g足够接近x。 考虑找到25的平方根。 1. 将g设为某个任意值,例如3。 2. 我们决定3*3 = 9不够接近25。 3. 将g设为(3 + 25/3)/2 = 5.67。⁴ ...
