In mathematics and computer science the floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to denoted or similarly the ceiling function maps to the least integer greater than or equal to denoted or. Constructing a 2 periodic extension of the absolute value function using floor and ceiling functions. The following formula takes the values in the total product cost column from the table internetsales and rounds down to the nearest multiple of 1. And this is the ceiling function.

R r must be continuous and monotonically increasing and whenever f x f x f x is integer we must have that x x x is integer. Unfortunately in many older and current works e g honsberger 1976 p. Certain functions have special properties when used together with floor and ceil. Int limits 0 infty lfloor x rfloor e x dx.

Definite integrals and sums involving the floor function are quite common in problems and applications. This function returns number rounded down towards zero to the nearest multiple of significance. Round towards minus infinity.
