Python divide as float

What is the Integer and Float Division in Python

To divide float values in Python, you can use the “/” operator. The Division operator “/” takes two parameters and returns the float division. Float division produces a floating-point conjecture of the result of a division.

If you are working with Python 3 and need to perform a float division, use the division operator.

Only a specific number of values after the decimal can be saved, so storing an exact binary description of many floating-point numbers is impossible.

Float division for Python 2

In Python 2, the only standard division operator is “/”. If both values are integers, the result is an integer. If either of the values is the float, the return is the float value.

To perform float division in Python 2, import the division package __future__ module and then use the “\\” operator to get the result.

from __future__ import division print(10 // 9)

In Python 3, the single slash (/) means proper division. The // operator is used for truncating division.

Adding a dot (.) operator indicates the floating-point numbers.

Integer division ( // )

The integer division operation // is used when you need to get the number as a whole number.

main_int_1 = 21 main_int_2 = 10 print("Result of integer division of two integers: ", main_int_1//main_int_2) 

Result of integer division of two integers: 2

Float Division in Python

Float division refers to a floating-point approximation of the result of a division or, mathematically speaking, the quotient. In comparison, integer division refers to an integer approximation of the quotient. Essentially, the floating part is completely removed from the result.

In statically-typed programming languages such as C , C++ , Go , Scala , and Java , floating division depends on the data type of the variables and the numerical values. Whereas, in the case of dynamically-typed programming languages such as Python , Groovy , PHP , Lua , and JavaScript , it depends on the numerical values (since variables don’t have a fixed data type and can be reused for a different type of values).

As stated above, Python is a dynamically-typed programming language. In this article, we will learn to perform float division in Python with the help of relevant examples.

Different Ways to Perform Float Division in Python

Essentially, Python has two ways to perform float division, and we will try to learn them through some examples. Note that the examples provided will try to cover most of the possible cases.

Using Default Division

In Python, the division performed by the division operation ( / ) is, by default, float division. To achieve integer division, one can use the // operator. Refer to the following code for some examples.

print(1 / 3) print(2 / 7) print(8 / 3) print(9 / 4) print(11 / 10) print(121.0 / 8.0) print(8 / 121) print(10 / 11) print(4.0 / 9) print(3 / 8.0)

Using Float Conversion

In Python and all the other programming languages, division of a float number ( float/int ) or division by a float number ( int/float ) or division of a float number by a float number ( float/float ), yields a floating-point result or quotient. Note that the same concept applies to the double datatype.

In Python, we can convert an integer or a string representing a number, both integer and float number, to a floating-point number with the help of the float() function. Let us look at some examples to understand how we can perform float division with the help of float conversion.

print(float(1) / 3) # float / int print(float("2") / 7) # float / int print(8 / float(3)) # int / float print(9 / float("4")) # int / float print(float(11) / float(10)) # float / float print(float("121") / float("8")) # float / float print(float("8.0") / float("121.0")) # float / float print(float("10.00000") / 11) # float / int print(float("4") / float(9)) # float / float print(float(3) / float("8")) # float / float

How to divide two numbers in Python

Here, we can see how to write program to divide two numbers in python.

• In this example, I have taken two numbers as number1 = 64, number2 = 8.
• To divide the numbers “/” operator is used.
• I have used print(result) to get the output.

number1 = 64 number2 = 8 result = number1/number2 print(result)

The below screenshot shows the output.

This code, we can use how to divide two numbers in Python.

Python program to divide numbers user input

Now, we can see how to write program to divide numbers user input in python.

• In this example, I have used the input() method. To take the inputs from the user.
• The result=number1/number2 is used to divide the two numbers.
• I have used print(result) to get the output.

number1=int(input("Enter the first number: ")) number2=int(input("Enter the second number: ")) result=number1/number2; print(result)

You can refer to the below screenshot for the output.

This is the code to divide numbers with user input in Python.

Python program to divide numbers using functions

Here, we can see how to write program to divide numbers using function in python.

• In this example, I have defined a function called div as def div(a,b).
• The function is returned as return a/b.
• The values to be divided are passed as the parameter in the function.

def div(a,b): return a/b print(div(27,9)) 

We can the division of 27 and 9 is 3 as the output. You can refer to the below screenshot for the output.

This is how to divide numbers using functions in Python.

Now, we can see how to write program to divide numbers using recursion in python.

• In this example, I have used the input() method. To take the inputs from the user.
• I have defined a function as def Div(number1,number2).
• The if condition is used, If the condition is true it returns as return 0. if the condition is not true it returns return 1 + Div(number1-number2, number2).
