Calculator

This calculator is a computer implementation of an electronic hand calculator.It offers the following additional features: A history pane offering the versatility of a control tape ("Tally roll"). You can copy the contents of this pane and paste it into your favorite word processor for printing. You can paste numbers into the main display and you can act upon them as if you typed them yourself. The value stored in memory is permanently visible in a separate memory display and immediately reflects any changes made to memory. The actual value of the main as well as memory display can be copied for use in another application such as a spreadsheet. Entries can be corrected: either entirely by clicking [CE] or pressing [Delete] on your keyboard or partially by using the backspace key. You can select whether results are rounded (zero or two decimals) or not (floating decimal separator). Calculator uses automatically the decimal separator selected in the regional settings of Windows. Independently from memory, you can set a number to use as a constant. You can then perform instant multiplications or divisions by this constant. This is particularly useful to quickly convert currencies.
