 VICalc Original "just-in-place" calculator Simply open any of your txt files or use an empty new one. Enter 2 plus 3 and press Enter. The result " = 5 " will be added automatically: 2 + 3 = 5 Use any of +, -, /, * operations: -2 + 3.5 = 1.500000 1 + 2 + 3 – 4 = 2 2 * 3 = 6 8 / 4 = 2.000000 1 * 2 * 3 * 4 = 24 8 / 2 / 2 / 2 = 1.000000 Change any of entered numbers and press F5 (or button "Refresh"). The whole content will be recalculated according your changes. You can save the document as a txt file or print out the document as usual. Then you can open any of saved files, make any changes and recalculate the content. Please add the extention (for ex. ".txt") to the name of file while saving it. You can use any comments or texts inside file: Expensies for August: income minus for wife minus for home minus for children minus for car is: 1000 – 100 – 200 – 300 – 150 = 250 You can use math functions: sin(30) = 0.500000 cos(60) = 0.500000 tan(45) = 1.000000 asin(0.5) = 30.000000 acos(0.5) = 60.000000 atan(1.0) = 45.000000 sqrt(16) = 4.000000 exp(1) = 2.718282 log10(10) = 1.000000 log(100) = 4.605170 fabs(-1.) = -1.000000 sinh(30) = 0.547853 cosh(60) = 1.600287 tanh(45) = 0.655794 To switch arguments to radians (for sin, cos etc), press the button "Radians". The whole content will be recalculated. You can open a lot of documents (files) together. Use menu "File / New" to open a new document. Use menu "Window / Tile" to arrange all opened documents. Tipps You can mix ["+" and "-"] or ["*" and "/"] operations: -1 + 2 – 3 + 1 = 0 4 * 2 * 1 / 2 * 2 * 2 = 1.000000 Please do not mix "+ -" and "* /" operations. The calculations are made from left to right, without priority of operations: 1 + 2 + 3 * 4 = 24 will be calculated as (1 + 2 + 3) * 4 = 24 and it is not correct! Do not use brackets in calculations. If anyone of arguments has fractions, the result will be shown as float: 1 + 2 + 3 – 1 = 5 1 + 2 + 3 – 1.0 = 5.000000
