Calculator++ requires Java Runtime Environment 6.0 or later. Scientists, engineers, programmers, and students will find it a simple to use, yet powerful, tool.Ĭalculator++ is written entirely in Java, so you can use it on the platform of your choice. Calculator++ supports over 25,000 units for conversion in an ever growing list of categories and units. While it serves as an excellent replacement for your operating system's built-in calculator, it also offers many powerful features that are not available together in any other handheld or computer-based calculator.
Using Calculator++, you can perform any of the customary handheld or online calculator operations, and many more. logarithmic and other complex functions - all at hardware speed.

With this PowerToy you can graph and evaluate functions as well as perform many different types of conversions.Ĭalculator++ is a cross-platform, arbitrary-precision, customizable, multifunction, scientific calculator. Even if you're just ciimching numbers and not matrices, the F- series has what it takes. It's not an installed replacement for a desktop calculator, but is nice when you don't have one available.ĮDIT: Couple more interesting ones for the astronomers: Aside from using Maxima for symbolic integration, I belive Sage uses Pari for highly optimised polynomial arithmatic, and I have used Sage for some pretty intense linear algebra computations (over the integers as well as over finite fields), although for this kind of thing you'll probably not want to rely on the online server which can be a little slow.Īnd let's not forget that you also get the moral boost of being part of something really positive-an movement to create an open source alternative to costly and "closed" alternatives like Mathematica, Maple and Matlab.Google does quite a bit of calculations and conversions, complete with built-in constants, from whatever browser you happen to have installed (assuing you're connected, but who isn't these days?). Although Sage is based on Python (so in particular any Python syntax will work), you really don't need to know Python to get started using Sage-I didn't when I started. I used the online notebook for around 6 months before I installed a copy on my own computer, and this was because I became interested in developing Sage. If complex numbers are disabled, this function is only defined for x > 0. Example: abs(-3 meter) 3 meter abs(4 + 3j) 5 sqrt (x) Return the square root of x.
(I just googled "sage notebook screenshot.") It's been designed to look and work like the Mathematica notebook system, and it's surprisingly slick and easy to use. When given a complex number as argument, it returns the modulus of the number. Here's a screenshot of what the notebook looks like.
This is a very popular option-I believe that in the last 9 months around 30,000 people have created accounts! It's perfectly suited for high school students and undergraduates, since no installation is necessary, and hence it can be used straight away in any computer lab with internet access. I think this is really nice-it feels like it's your "gmail" but for maths, so you can just log in from anywhere and "check your maths" if you want :-D Calc98alc98 is freeware calculator includes functions for statistics, use of different number bases (binary, octal, hexadecimal and base-n), metric units.

This is true, the binary downolad comes in at around 1 gig, however you can use it for free online, without having to install a thing! Head on over to, and sign up for a free account, which will allow you to create and save your own worksheets. Firstly someone mentioned that Sage is quite large to install. A few people have mentioned Sage, but I think deserves a bit more of a plug.
