Works Like Windows 7 Calculator
Built to rhyme with the Windows 7 Calculator, the version many people consider the best ever shipped. The equals key repeats the way it should, your last hundred calculations are just one click away, and every calculator function result behaves the way you expect.
Press Equals Again - It Repeats
Type 4 x 16 = and you get 64. Press = again and it keeps multiplying by 16: 1,024, then 16,384. Set the operation once and use the Equal button or key to repeat that operation on the
result. Or, enter a new number and press the = to have the last operation applied to it. It's a feature serious calculator users rely on, and one that many online
calculators get wrong . . . How Equals Key Works
Calculation History - One Click Away
Your last 100 calculations are saved to a scrollable history, ready when you need them. Click a calculation in the history and the calculator picks up there, with that result on the display so you can keep going . . . More About Calculation History
Run It Entirely From The Keyboard
Twenty-three keyboard shortcuts mean you don't have to reach for the mouse. There are even eight mathematical constants: π, e, the golden ratio and more, each a single keystroke away for the people who need them . . . View Keyboard Shortcuts
Leave and Return - It Remembers
With Save Work 'on' (the default), everything you do is saved to your browser as it happens: your display, your history, your memory, your settings. Close the tab in the middle of a calculation and reopen it tomorrow, right where you left off.
Keeping Calculator In View
Click the word Calculator above the calculator display and it scrolls into view, sized to fit the height of your browser window. Handy when there's a header or other content above the calculator and you just want the tool itself front and center.
