ULP 即 "Unit in the Last Place" 的缩写。 另请参阅 math.nextafter() 和sys.float_info.epsilon。 3.9 新版功能. 注意frexp() 和modf() 具有与它们的C等价函数不同的调用/返回模式:它们采用单个参数并返回一对值,而不是通过 '输出形参' 返回它们的第二个返回参数(Python中没有这样的东西)。 对于ceil(...
Do you need to round up a number to the nearest integer? Do you need to get the ceiling of a given number? If yes, then you are in the right place. This tutorial helps you understand and learn how to use Python math.ceil() function. ...

Thepow(x,y)function returns the value of x to the power of y (xy). Example Return the value of 4 to the power of 3 (same as 4 * 4 * 4): x =pow(4,3) print(x) Try it Yourself » The Math Module Python has also a built-in module calledmath, which extends the list of...
Python def fact_loop(num): if num < 0: return 0 if num == 0: return 1 factorial = 1 for i in range(1, num + 1): factorial = factorial * i return factorial You can also use a recursive function to find the factorial. This is more complicated but also more elegant than using...
FunctionReturnsExample abs(x) Returns the absolute value of x. {% codeblock lang:python line_number:false %} x = -35 x = abs(x) print(x) {% endcodeblock %} cmp(x,y) Returns -1 if x < y Returns 0 if x equals to y Returns 1 if x > y. {% codeblock lang:python lin...
Anoperatoris a symbol or function that indicates an operation. For example, in math the plus sign or + is the operator that indicates addition. In Python, we will see some familiar operators that are brought over from math, but other operators we will use are specific to computer programming...

Using the add() function: [ 3 7 11 15] In the above example, first we created two arrays named: first_array and second_array. Then, we used the add() function to perform element-wise addition respectively. To learn more about the Arithmetic Functions, visit NumPy Arithmetic Array Operatio...
