Question about Texas Instruments TI-84 Plus Calculator
Hi, I am trying to figure out if the TI-84 calculator is able to do "greatest integer fuction" problems on it. Whenever possible, I just wanted to know if you can help me in telling me how to find it in the calculator.
Thank-you so much =D
The greatest integer function (also called a step function) is actually a piecewise defined function with a special definition. The function has the notation f(x)=||x|| or f(x)=[[x]] when it is written, but the TI-83 and the TI-84 designate this function by using f(x)=int(x) and is found in the MATH NUM menu. This function is the greatest integer less than or equal to x. So, f(1)=1 and f(1.4)=1. Since this is a piece-wise function you should use DOT mode.
