To convert integer to float in Python, we can use the float() builtin function or implicit conversion. In this tutorial, we shall go through these two methods of converting an integer to a float. Method 1: Int to Float using float()float() builtin function can take an integer as argument and return a floating-point number with the value as that of the given integer. In the following program, we will take an integer, and convert it to float. Python Program
Run Output
Method 2: Int to Float using Implicit ConversionImplicit conversion is the process where Python interpreter converts the given int to float when the int is added/subtracted/etc., with a floating-point number. In the following program, we take an integer value, add it to a floating-point zero, and Python Interpreter takes care of the conversion. Python Program

SummaryIn this tutorial of Python Examples, we learned how to convert or implicitly typecast value of int datatype to that of float, with the help of well detailed example programs. Related Tutorials
Hello coders!! In this article, we will learn the conversion of int to float data type in python. At first, we should understand the difference between the two. What is type casting?It may happen during programming that one feels the need to change the data type of a certain variable to some other specific data type for better performance and match the data type of given operation. Type casting is of two type:
Implicit data conversion from int to float:Implicit data conversion is done by Python itself either during compilation or during run time. a = 1 print('Data type of a:',type(a)) b = 1.0 print('Data type of b:',type(b)) c= a+ b print('Sum of a and b:',c) print('Data type of their sum:',type(c)) Output & Explanation:OUTPUTIn the above code, we took two variables, one of type int(‘a’) and the other of type float(‘b’). When we added these two variables, the result variable was seen to be of data type float. So, the int to float conversion occurs implicitly here as float has higher precision than an integer. float() is an in built function available in python that is used to convert the variables from int to float. a = 1 print('Value before conversion:',a) print('Data type:',type(a)) b=float(a) print('Value after conversion',b) print('Data type:',type(b)) Output & Explanation:In this example, we took an int variable ‘a’ and assigned it the value 1. We then used the float() method to convert it into a float value. We can clearly see from the output the conversion of an integer variable to float. Alternative for Implicit Conversion of int to float [Explicitly]:a = 1 print('Value before conversion:',a) print('Data type:',type(a)) a = a+0.0 print('Value after conversion',a) print('Data type:',type(a)) Output & Explanation:As we can see, in the given code, we have indirectly used the explicit type conversion to convert variable ‘a’ into float by adding a decimal of 0.0. As float has higher precision, the value of the variable is converted into a float data type. Must Read:
Conclusion:In this article, we learned about type casting and saw how to explicitly and implicitly type cast int to float in Python programming. However, if you have any doubts or questions, do let me know in the comment section below. I will try to help you as soon as possible. Happy Pythoning! Does Python default to float?The most important data type for mathematicians is the floating point number. By default, python interprets any number that includes a decimal point as a double precision floating point number.
How do you convert an int to a float in Python?To convert the integer to float, use the float() function in Python. Similarly, if you want to convert a float to an integer, you can use the int() function.
Does Python automatically convert types?Python automatically converts one data type to another data type. This process doesn't need any user involvement Python promotes the conversion of lower data type, for example, integer to higher data type says float to avoid data loss.
Can an int become a float?Yes, an integral value can be added to a float value. The basic math operations ( + , - , * , / ), when given an operand of type float and int , the int is converted to float first. So 15.0f + 2 will convert 2 to float (i.e. to 2.0f ) and the result is 17.0f .
