Using the sqrt() function defined in math module of the Python library is the easiest way to calculate the square root of a number.Algorithm (Steps)Following are the Algorithm/steps to be followed to perform the desired task −Use the import keyword to import the math module. Create a ...
# importing the module import math x = 6 + 4j res = math.sqrt(x) print( "The square root of a complex number is:", res) Output of the above code is as follows −Traceback (most recent call last): File "C:\Users\Lenovo\Desktop\untitled.py", line 4, in <module> res = math...
You can solve this equation using the Python square root function: Python >>>a=27>>>b=39>>>math.sqrt(a**2+b**2)47.43416490252569 So, Nadal must run about 47.4 feet (14.5 meters) in order to reach the ball and save the point. ...
epsilon越接近0,算出的方根值就越精确。 调用此函数试一下,同时与python自带的sqrt函数进行对比: print(sqrt_bi(8)) import math print(math.sqrt(8)) 运行结果如下: 2.82842712474619 2.8284271247461903 python自带的sqrt函数比sqrt_bi函数还要更精确一些。 参考:麻省理工学院公开课:计算机科学及编程导论(第5课)...
In this guide, you'll learn how to calculate the square root of a number in Python, using math.sqrt(), np.sqrt(), pow(), math.pow() and the ** operator, with a performance benchmark.
导入数学模块只会发生一次,并且您可能不会比数学模块快得多。还有一个较旧的stackoverflow问题 哪个在Python中更快:X **。5或Math.sqrt(x)?。尚不清楚哪种方法更快。 也许看看 numpy. 和scipy,不一定是SQRT,但如果你正在做一些沉重的计算,他们可能很方便。智能...
