Pros

If you don't have Java installed on your PC, the calculator won't run.

Cons

Can not test, there's no Java on my PC.

Happy to report that this program no longer needs Java.

Pros

Not only it calculates fast but the user-interface allows you to type expressions very quickly and see the result instantly.

Cons

More built-in functions would be nice, although you can define your own functions which is good.

Pros

Excellent editor's review and good users' reviews. Free.

Cons

Not very clear user interface and unclear limits of calculations.

Summary

I have tried this calculator for sin(x), cosh(x), atanh(x), ln(x) . For x=1 sin(x) returned about 50 digits. It shows that the author somewhat uses high precision arithmetic. But cosh(x) returned only 16 digits. Atanh(x) returned n/a . For x= 1E4 ln(x) was calculated a few seconds, cosh(x) returned n/a . For x=1E40 ln(x) entered a long loop. After 10 min of waiting I closed the calculator.

Probably good enough for entry level college students. Definitely not good for engineering and science.

Thank you for this comment. Indeed when dealing with high precision computations we need to choose a solution that is well balanced between speed and precision. Our calculator started with 16 digit limit for all calculations and we're progressively moving forward toward making all available functions computable to 1000 digits and beyond within fraction of a second. We estimate that all functions will be high precision by next version (3.2) and speed will be improved by version 3.4. president@runiter.com

Pros

More than lives up to the CNET editors' review and the publisher's description. The program's features proved more than adequate for a college-level calculus course. Unlike the calculator included with Windows, the interface is clearly visible.

Cons

If it has a simple, one-step "clear" button I haven't found it.

I found it.

No cons.

Pros

I find it convenient for the sort of calculation in which one changes one variable many times while keeping others constant. One could do the same thing in a spreadsheet, but sometimes a spreadsheet is more than one needs.

Cons

I probably haven't tried most of the features. I don't want to take the time to learn things until I have a need. This is a con only in the sense that it would take some time working with this to really use it efficiently.

Summary

I tend to use this instead of any of the several more conventional calculators I have on my computer. It saves me a few keystrokes; every little bit counts.

Pros

Product is exactly as advertised. The library feature and interface are outstanding.

Cons

Once installed it took a moment's effort to keep it out of my task bar and startup, but that may have just been something I missed during installation.

Dear expectdelays, thanks for the kind feedback. The startup option is enabled by default and can be easily disable by checking it off in Settings panel (The icon in the lower right side of the window). In your opinion do you believe that the startup should be disabled by default?

Thanks,

Pros

Great if you need a calculator that does more than the built-in windows calculator. Allows you to declare variables, create your own functions, and use them in calculations. You can write formulas out in their entirety then press calculate.

Cons

No graphing.

Summary

This is essentially a software version of a high-end calculator. This calculator lets you see results as fractions. For example: -3/7 as apposed to -0.4286. I'm also a visual guy. I like to write out my entire equation. For example: ((7+SIN(3))-(7*SIN(3)))/2. You can't do that in the built in windows calculator, even in scientific mode. Every time you close a parenthesis in the windows calculator, it computes that step, thus making it difficult to remember your place, especially on long equations. The history feature, plus the ability to save equations, formulas, and variables. For example, lets say you have a linear equation 7x+3=1. You can declare two functions: fx(x)=7x+3 and fy(y)=(y-3)/7. To find the value of X when Y=0, just type in fy(1) and the answer appears. Nifty. Of course, this requires you to know a little bit about math ahead of time.

Thanks for your feeback mrbinky3000. We actually do have a Graphing Calculator that is built on top on this Math Calculator. You can read about it or download it here:

Pros

A very good performance and an easy way to do Calculations.

Cons

No cons. I like it very much.

Pros

It gives a running total during complex calculations.

Cons

You close the program--you get a 'you want to quit' button. You click 'yes'. Program terminates. Then browser laods. wait. Kill browser. If Mozilla is already loaded, it forces IE7 to load. You encounter this EVERY TIME you close the program!

Summary

The Cons for me (see above) far outweighs any benefit. This the most PASSIVE AGGRESSIVE marketing approach that I have so far encountered with freeware. Forget it, there are other free desktop calculators which don't put me 'through the hoops' when I want to close them. Thanks but no thanks!

Thanks for taking the time to report these issues. Forcing IE7 to load is not a normal behavior and is certainly not intentional. We will look into it. We will also look into ways of making the exiting from application more pleasurable through reducing or eliminating the hassles you mentioned above. These improvements will be available in version 1.7. For more information or more suggestions feel free to email me at support@runiter.com

Pros

It's easy to balance a check book all in 1 line of code without stopping to sub total.

Cons

More than I need

Summary

Excellent at what it does
