在Python编程中,取余(Modulus)和取商(Floor Division)是处理数字时常用的操作。理解这些操作对于任何一位程序员来说都至关重要,因为它们能够在许多情况下简化代码和逻辑。本文将探讨这两种运算的原理、用法以及实际应用场景。 取余运算 取余运算符是%,它返回两个数相除后的余数。下面是取余运算的基本语法: result=a%b 1. 例子
(一)Floor division 和求余(modulus) //运算符先进行除法,之后将结果保留到整数; /运算符是保留小数的,生成一个float类型的数; %求余运算符,将两个数相除,返回它们的余数; (二)布尔表达式(boolean expressions) 布尔表达式的结果是true或者false; ==是关系运算符之一; 其他关系运算符:!=,>,<,>=,<=; (...

print (a / b) # division print (a % b) # modulus print (a ** b) # exponentiation print (a // b) # floor division 所有操作都很容易理解。模运算返回除以两个数的余数(在我们的示例中,4是提示)。同样,底数除法是整数除法,它返回除法结果为整数(10 // 6 = 1)。
As you can see, neither addition nor division changes the value of math.inf.Not a Number (NaN)Not a number, or NaN, isn’t really a mathematical concept. It originated in the computer science field as a reference to values that are not numeric. A NaN value can be due to invalid ...
print("Modulus:", mod_result) # Power Operation exp_result = a ** b print("Exponentiation:", exp_result) # Floor division floor_div = a // b print("Floor Division:", floor_div) Output: Explanation: Here, we perform different arithmetic operations on two numbers and print the results...
Python >>> 5 >> 1 # Bitwise right shift 2 >>> 5 // 2 # Floor division (integer division) 2 >>> 5 / 2 # Floating-point division 2.5 The bitwise right shift operator and the floor division operator both work the same way, even for negative numbers. However, the floor division ...
Now we know that the remainder can be determined with the help of the modulus function (%), which returns the remainder of the division. Now, let’s go ahead and write the program. Python Copy Code Run Code 1 2 3 4 5 6 7 # Defining the Function def EvenOdd(n): print("Even ...
