However, consider this calculation and its result:

(262144 * 4096) - (2^18 * 2^12) = -0.01

The correct answer, obviously, is 0. That may be a silly calculation to perform, but I actually did this once as a check.

TI's support - via email - suggests that this is a normal rounding error. I am not sure that this is acceptable in a calculator of this class. The size of the operands doesn't seem unreasonably large.

If it were not for that, I would give the calculator 4 stars. It's really too bad because I like the layout of this calculator MUCH better than that of the Casio. But I worry about getting other errors that won't be immediately obvious to me.

I can't prove one or the other how likely this rounding error is to happen in "typical" calculations.

GREAT calculator especially for those in elementary, middle, high schoolJun 21, 2006

Ok I'm a high school student and got this calculator last year for honors chem, my other scientific calculator (TI-30X) just wasn't sufficient. But this one is great! If you're in chemistry, it has easy-to-use conversions (from pounds-kilos, gallons-liters etc.), and for chem and other sciences like bio, and physics it has constants such as Avogadro's number and Planck's constant, which make solving problems easier. Plus, for math, it's the easiest scientific caluclator I have encountered, and has many features. The only drawbacks I can see are that it does not have a two-line display and you cannot go back and see previous operations and the snap-on cover is a bit awkward at first. However, the screen is easy to get used to, and once you do, the calculator is perfect. For students, this has all the features which you need up through Alg 2 and trig (and probably further) and is simple to use. Plus, you can use it on the PSAT, SAT, SAT II's, ACT, AP exams! Though other users may be right that you can find cheaper calculators with more features from brands other than TI, I would say that for those in elementary, middle, or high school, its easiest to stick with TI, that's what everyone else, including the teacher uses, and that's what the teachers in my classes have always taught us how to use new features using TI. By far I would say its the best scientific calculator with the most useful features that I have encountered, and your best bet if you are still a student.

An amazingly functional calculator.Jun 03, 2000
By C. Grantham
I have used the TI-36X, which I bought several years ago after I lost the similar TI-35X. This calculator is excellent for everything from Pre-Algebra to Pre-Calculus. I have a feeling that it won't be as adequate for college-level calculus, but the graphing calculator I use (TI-82) is less intuitive and more cumbersome. For $25, the TI-36X should be good for five years of math through trig and statistics. It's the standard too. Most teachers are familiar with its layout, as opposed to the more obscure Casios.
