Floor, ceiling, and truncate in Python

I am working on a music player which has a strict Source Lines of Code (SLoC) count. When looking for ways to lower that count, I discovered that I was importing the math module, just to floor a variable. In an attempt to remove the import statement, I looked at the official documentation for math.floor, and I saw this:

...If x is not a float, delegates to x.__floor__, which should return an Integral value.

math.floor

x.__floor__

Integral

When I went to the x.__floor__ link, I found this:

object.__round__(self[, ndigits])

object.__trunc__(self)

object.__floor__(self)

object.__ceil__(self)

Called to implement the built-in function round() and math functions trunc(), floor() and ceil()....

Basically, instead of running the following:

import math

float_value = 4.72
print(math.trunc(float_value)) # 4
print(math.floor(float_value)) # 4
print(math.ceil(float_value))  # 5

you can instead run the following:

float_value = 4.72
print(float_value.__trunc__()) # 4
print(float_value.__floor__()) # 4
print(float_value.__ceil__())  # 5

getting rid of the math dependency, and importantly in this case, one line.
