Freeware Calculators!

This happens to me all the time: I'm working on my computer and I need a calculator. The calculator that comes with Windows is, to say the least, quite lame. There are several available, some of which are specialized for graphing, financial calculations, or specific scientific needs. But if you just need a calculator with basic functions, for free, here are some options (if your keyboard supports it, you can program a button on your keyboard to open the calculator when pressed):

Karen's Calculator ~ A high-precision Unlike ordinary calculators, it returns completely accurate results, even with operands containing thousands of digits. If you're patient, operands and results containing hundreds of thousands of digits are possble too! Most calculators are only accurate when dealing with numbers containing a few digits -- usually 16 to 32. When asked to calculate using larger numbers, they either fail (displaying an error) or return results that are only approximately accurate. Karen's Calculator can easily handle numbers and results containing many thousands of digits with complete accuracy. It also includes an on-screen "tape" -- which can be saved to disk -- versatile memory features, and more!

SkinCalc ~ SkinCalc is a free skinnable calculator with more than 100 different skins available for download. Skins make it possible to change the layout and functionality of the software.

Joey's Mathematical Calculator ~ Developed straight from the basics of the old Scientific Calculator comes the Mathematical Calculator (MathCalc). Whether it's solving a mathematical or boolean expressions or simply computing Geometric and Trigonometric values, this calculator will get the job done. This calculator also features a base converter (convert between bases 2 to 62 interchangably!) and a polynomial constructor (plug in some points - get back an equation that follows through each of those points). MathCalc will never cost anything. Updates will be put out from time-to-time to port over features from the old SciCalc that would be most useful in MathCalc. MathCalc will also be updated in the event that a new brand feature should be added.
