In the Python math library, the math. floor and math.trunc. Do the same thing?. And what's the difference?

Question

Import math
math.floor (5.9) = 5
math.trunc (5.9) = 5

Answer 1

There wouldn't be two different methods if they did the same...

trunc() gets rid of all decimal places: trunc(4.123) = 4
floor() rounds down to the next smallest integer: floor(4.123) = 4

The difference gets obvious when you use negative numbers:

trunc(-4.123) = -4
floor(-4.123) = -5

Answer 2

In a more technical way:
trunc() rounds up or down towards zero.
floor() rounds down towards negative infinity.
