Topic: Step Functions (a.k.a Greatest Integer Functions)

I've been tooling around for an hour and still can't figure this one out either.

Step Functions - the result of the graph is supposed to look like stairs or steps and I haven't been able to reproduce that result. 

Example: f(x)=[1/2x + 1]

I have tried using the "FLOOR" syntax but that hasn't worked for me.  I have also tried INT and INTG. 

Any suggestions?

Thanks again for your time.


Re: Step Functions (a.k.a Greatest Integer Functions)

I am a little unsure which function [x] denotes, but you probably want one of these: ceil(x), floor(x), round(x,0) or trunc(x). You can find more information about the rounding functions in the help:
