Properties Of Floor And Ceiling Functions
The wikipedia page floor and ceiling functions furthermore lists a lot of properties very few proofs or derivations though.
Properties of floor and ceiling functions. The function is a piecewise constant function with unit jumps on the lines the function is continuous from the right on the intervals and from the left on the. The floor and ceiling functions and are piecewise constant functions with unit jumps on the lines the functions and are continuous from the right from the left on the intervals and from above from below on the intervals. The int function short for integer is like the floor function but some calculators and computer programs show different results when given negative numbers.
For example the floor and ceiling of a decimal 3 31 are 3 and 4 respectively. Definite integrals and sums involving the floor function are quite common in problems and applications. The ceiling function is usually denoted by ceil x or less commonly ceiling x in non apl computer languages that have a notation for this function.
0 x. One is the floor function and the other is the ceiling function. So with the help of these two functions we get the nearest integer in a number line of a given decimal.

The j programming language a follow on to apl that is designed to use standard keyboard symbols uses. And this is the ceiling function. In this article let us discuss the ceiling function definition notation properties graphs.
