This function is also known as the floor function.
Greatest integer function math. Greatest integer function is not invertible. The greatest integer function also called step function is a piecewise function whose graph looks like the steps of a staircase. A function f of mathbb r in mathbb r is a function of the greatest integer that is less than or equal to x if and only if. The domain of greatest integer is r and its range is z.
Viewed 3 times 0 i came across this set builder definition for the greatest integer function which is also equal to the floor function in my discrete mathematics course indicated below. That makes sense but it s a little confusing. These functions are normally represented by an open and closed bracket. The greatest integer function is represented denoted by x for any real function.
For example and while. What is the greatest integer function. 1 15 1 4 56567 4 50 50 3 010 4. These values are the rounded down integer values of the expression found inside the brackets.
