This is incorrect. the int function will remove the floating point portion of the number which is not the same as the floor function, as the floor function will always round down to the next whole integer. while they will give the same result for positive numbers (int(2.7) = 2 and floor(2.7) = 2) they will give different results for negative numbers. int(-2.7) = -2, but floor(-2.7) = -3.
