7/23/2023 0 Comments Simple calculator online![]() Getting around this would mean to programm a high precission calculation engine which would slow down the calculations dramandously and blow up the script, or to send the calculations to an external calculator (as web services, Ajax request or so) which would aslo slow down the calculations and would make this calculator an 'online' programm, which you probably wouldn't want to have. See following links that explain this situation more precise: It does this by using a smaller presision value and using some of the bits as a exponent (this can also be done in 16 bits with a smaller range and less presision) which results in it being able to approximate any value in the range but not exactly represent them all (because in real number terms the are an infinaite number of values between any 2 given values).Īs part of your calculcation clearly the internal representation of the value is going outside the available presision and you are ending up with an approximation to the value instead of an exact value. Any language using this definition suffers from this 'feature', for instance C does as well and since JavaScript is often implemented in C so does JavaScript. This isn't actually a Javascript feature but a feature of the way the IEEE define how floating point numbers are stored in memory. This is due to a 'problem' with how JavaScript handles floating point numbers. This calculator operates with a precision of (only) 15 digits after the decimal point. Mouse handling mimics the handling of the iPhone™ Look and feel of the well known iPhone™ (OS4) calculator.No need to close brackets if equation sign follows anyhow.You can theoretically use an unlimited amount of brackets.not 8 like with the original iPhone™ calculator) Real sci-calc-style calculations, so 1+2*3=7 (.All keybord shortcuts work in both modes! Simple / Scientific toggle: click arrow in a circle on left side of display orĭoubleclick display or press to toggle. ![]() Dynamic font-size in display to keep numbers as readable as possible.Digit grouping in 4 modes:, , or switchable with the new circle on the left or.Copy/Paste from/to display with Ctrl+C and Ctrl+V.Full Keyboard support: See Using the Calculator.It's even possible to continue a calculation sequence after turning it off/on Memorizes not only the display if turned off/on but also all other states.Uses very little memory if in use (no images, event delegation.).(most extensions use memory just by running in the background and slow down your Google Chrome™ browser and make it 'heavy') Uses no memory if not in use, so don't bother having Calc SS3 installed.See for a clean and nice 1-file demo of Calc SS3 ^ back to top Features Calc SS3 can be installed directly from Google or from the Google Chrome web store:
