How to convert int to float in Python?

integer to float conversion in python

You can use the Python built-in float() function to convert an integer to a float. Pass the integer you want to convert as an argument. The following is the syntax –

# convert integer i to float

It returns the number as a float value.


Let’s look at some examples of using the above syntax to convert an integer value to a float.

Here we apply the float() function on an integer value 12.

# integer variable
num = 12
# convert integer to float
num = float(num)
# display the number and its type


<class 'float'>

You can see that the variable num is of float type now with the value 12.0.

Alternatively, you can perform an arithmetic identity operation on the integer with a float value to get the resulting value as an integer. For example, multiply or divide the integer by 1.0 or add or subtract 0.0 to get the same value but as a float.
