Floor Function and Ceiling Function - Definition, Formulas, Properties, Examples
The floor function is denoted by floor(x) or \(\lfloor x \rfloor\). Also sometimes the floor function is represented using double brackets and is written as [[x]]. An example of floor function is \(\lfloor 2.3 \rfloor\) = 2, and \(\lfloor -3.4 \rfloor \) = -4. Ceiling Function: It is a function that takes an input as a real number and gives an output that is an integral value greater than the input real number.
