Practice: Mixing Ints and Floats

Mixing and Converting Between Integers and Floating-Point Numbers

In Python, you can convert an integer value to a float value by using the built-in float( ... ) function:

float(12)

• Will convert the integer value 12 into the float value 12.0 and return it.

You can also convert a float value into an integer value by using the int( ... ) function:

int(12.0)

• Will convert the float value 12.0 into the integer value 12 and return it.

One thing to keep in mind when converting float values into integers is that the new integer will drop any fractional part.

For example:

int(365.26)

• Will convert the float value 365.26 into the integer value 365 and return it. This means the .26 value is lost.

Practice: Number Type Conversion

With the above information about integer and float values in mind, complete the following steps.

1. Define a variable named months_as_float, and assign it 7.28.
2. Print the value contained in the months_as_float variable.
3. Define a variable named months_as_int, and assign it the value of months_as_float converted to an integer.
4. Print the value contained in the months_as_int variable.
5. Define a variable named months_as_float_restored, and assign it the value of months_as_int converted to a float.
6. Print the value contained in the months_as_float_restored variable.

> 
7.28
7
7.0

months_as_float = 7.28
print(months_as_float)

> 7.28

months_as_int = int(months_as_float)
print(months_as_int)

> 7

months_as_float_restored = float(months_as_int)
print(months_as_float_restored)

> 7.0

When you have completed the above, you are ready to move on to the next exercise!
