Google TI-83 online or TI-83 emulator to find some downloadable or browser graphing calculators. I think Casio still makes a really inexpensive graphing calculator, if you'd rather use the physical object.

The floor function will work to give you the integer part of a function f(x) like this: floor(f(x)).

If you need to remove the integer part and keep only the decimal part, you do this: f(x) - floor(f(x)).

Here's a sample graph that illustrates the idea https://www.desmos.com/calculator/pwimnahrpb

I'm having trouble understanding some of your post, but I hope you eventually find what you are looking for. WolframAlpha might be better for your needs. You can get 15 day free trials of Mathe... [ More ]

in programming I use int or intergerpart() to remove the integer portion it has something called floor. it is not the sato me. it does not have the ability. nor does it have the abliiity to except the transform i need to put in for oounform output. I wish to see output in final form.

I'm looking into some others graphing calculators. some are more complicated then need be. wolframalpha is on online only.

I like desmos but I find it lacking programabilty of any kind. its just one line eq. p... [ More ]

Could you clarify a little more? What functions does it not graph? I have used Desmos often to produce images and as far as I've seen it will graph any number of 2-dimensional equations. Not just lines like y = mx + b, but also trig, inverse trig, exponential, power, logarithmic, polynomial, and functions of the form f(x)/g(x).

Are you trying to use more esoteric functions that don't have closed-form expressions in terms of the functions listed above -- like erf, gamma, functions defined in... [ More ]

I need a new graphing progam with more features then the free app called desmos program freely distributed on the web.

do you know of any?

perhaps they may be opensource or whatever.

desmos is a math function graphing program. however it does not have enough functions.

desmos graphs a line or whatever one line equation you give it.

however i need it to have more math functions.

Any sugestions other than excell would be helpful.

thankyou in advance,.
