Floor Function Discrete Math
But many calculators and computer programs use frac x x int x and so their result depends on how they calculate int x.
Floor function discrete math. For example 5 5 6 359 6 7 2 π 3 13 42 14. Mathbb r to mathbb z. The input to the floor function is any real number x and its output is the greatest integer less than or equal to x. The notation for the floor function is.
Functions floor function the floor function assigns to the real number x the largest integer that is less than or equal to x. The floor function also known as the greatest integer function. Floor x x examples floor 2 1 2 1 2 floor 3 3 3. R z of a real number.
Some say frac 3 65 0 35 i e 3 65 4. If x and y are positive numbers both are less than one then maximum value of floor x y is. We introduce the floor and ceiling functions then do a proof with them. X x denotes the greatest integer less than or equal to.
Frac x x floor x so. The value of the floor function at x is denoted by x. Floor function f x is the largest integer not greater than x and ceil function f x is the smallest integer not less than x. Frac 3 65 3 65 floor 3 65 3 65 4 3 65 4 0 35.
For example and while.
