You need to make one of the inputs a floating point value. Try changing 2 to 2.0. E.g.:
>>> x=10
>>> x**2
100
>>> x**2.0
100.0
Note that in Python 3 division automatically returns a floating point, and the new // operator explicitly does integer division.

You generally don't round until you go to display the value. You can use round for that, but since you just want to display it with two digits, you can use string formatting . In your case, something like print(f'{totalPay:.2f}'). .2f is the format specifier, saying round the float (f) to two decimal places (.2). More on reddit.com

September 18, 2025 - In Python, the float() function is used to convert numbers or numeric strings into floating-point numbers. A floating-point number is simply a number with a decimal point (for example, 3.14, -0.5, or 10.0).

Python Float - Initialize
To initialize a variable with float value, use assign operator and assign the floating point value to the variable. Variable name has to be on the left hand side and the float value has to be on the right side. In the following Python program, we have initialized variables x and y with float values.

Hola,
So the question says
create a function add the two arguments and returns their sum
```python
def add(x , y):
return x + y
```
At this point we assume we are just adding numbers together.
Let's make sure we're always working with floats. Convert your arguments to floats before you add them together. You can do this with the float() function.
Ok let's make sure no matter what comes in it's converted to a float
```python
def add(x , y):
a = float(x)
b = float(y)
return a + b
```
Ok now I converted each value to a float. It could be any whole number or float passed in, and no matter what it is, I am going to turn it into a float.
BUT WAIT? What happens if I pass in a string? That can't be converted to a float. When a string like "hello" is converted into a float, it fails. It gives you a ValueError. Meaning the value can't be converted to float. can't convert a text string into a float. So we catch that and return nothing. Otherwise we were able to convert them both successfully and return true.
This might be the 3/3 in the challenge I think.
```python
def add(x, y)
try:
a = float(x)
b = float(y)
except ValueError:
return None
else:
return True
```
Let me know if this makes sense or not. If not I can attempt to approach it another way.
Thanks!

August 6, 2022 - Some of the basic native types in python are strings, integer, complex numbers and finally floating-point numbers. Focusing on the floating-point type, the native Python float() method is used to create a float type object as well as to type-cast any other type to the corresponding float.

02:02 So, obviously, in that case, 10 divided by 4 is 2.5, so the answer would need to be a floating-point number, but if d is redefined to be 5, and we make f = c / d again, 02:19 we can see that f is a float even though the answer could be an int. Python does have the integer division operator, which is the double divide sign (//), as seen here, and we can see the result is 2.

15. Floating-Point Arithmetic: Issues and Limitations — Python 3.14.3 documentation
Historically, the Python prompt and built-in repr() function would choose the one with 17 significant digits, 0.10000000000000001. Starting with Python 3.1, Python (on most systems) is now able to choose the shortest of these and simply display 0.1. Note that this is in the very nature of binary floating point: this is not a bug in Python, and it is not a bug in your code either.
