floor() and ceil() function Python - GeeksforGeeks
Note: Both functions require importing the math module: import math ... Both return an integer. Let’s take a list of floating-point numbers and apply both floor() and ceil() to each value.

4 weeks ago - If x is not a float, delegates to x.__floor__, which should return an Integral value. ... Fused multiply-add operation. Return (x * y) + z, computed as though with infinite precision and range followed by a single round to the float format. This operation often provides better accuracy than the direct expression (x * y) + z. This function follows the specification of the fusedMultiplyAdd operation described in the IEEE 754 standard.

since using a for loop can only check the integer roots Finding integer roots seems like all you need if you are looking for the floor of the square root. If you start at zero, and check every integer for i*i >= x, the first i for which that would be true would be the ceiling of the square root. Then you just need to decide if x is a perfect square (return i), or not (return i - 1). For example, if you are looking for sqrt(10), i*i >= 10 becomes true when i is 4. Because i*i is not actually equal to 10 (because 10 is not a perfect square), you know that the floor of the square root is 3. If you want to get more efficient and mathy, you could use Newton's method. You are looking for x such that x2 = a. Another way of saying this is that you are looking for x such that f(x) = x2 - a is zero. The derivative of this is f'(x) = 2*x. Now Newton's method tells us to just repeatedly execute: x = x - f(x) / f'(x) This should converge on the square root. More on reddit.com

July 21, 2024Why does round(0.5) = 0?
Specifically, because it uses the "ties to even" rounding rule (there is more than one rule allowed by the IEEE standard) as it's more fair statistically

August 24, 2016Why not always use Math.round instead of Math.floor?
Well, they are two different functions, with two different uses. Math.floor() always rounds down to the nearest integer, while Math.round() will round up or down depending on what side of .5 the number falls on. So, the basic answer is that you use which one gets the result you expect. When it comes to generating random numbers though, Math.floor() has a more even distribution than Math.round(). If you want to generate a random number between 0 and 2, take the following examples: Math.floor(Math.random() * 3). Here, 0-0.999999 will give you 0, 1.0 to 1.999999 will give you 1, and 2.0 to 2.999999 will give you 2. Every number has a 33% chance of being the result. Math.round(Math.random() * 2). Here, 0-0.499999 will give you 0, 0.5 to 1.499999 will give you 1, and 1.5 to 1.999999 will give you 2. Note that the range of numbers that lead to a 1 is twice as big as those that lead to 0 or 1. That is 25% chance of 0, 50% chance of 1, and 25% chance of 2. More on reddit.com

February 22, 2017What is the floor function in Python?
The floor function in Python rounds a number down to the nearest whole integer. It’s part of the math module and is useful when you need consistent rounding toward the lower integer value in calculations.
