By clicking on the 'calculation' button, the formula entry is also written to a file in the '.\\_\\_log\\_\\_' and 'calc.py' starts running, and writes the calculation and the result in files into the '.\\_\\_log\\_\\_'.\nVariables can be overwritten.\n\nBy selecting a format behind 'Safe used Formula for' the used formula for error propagation is written into a file named 'saved_formula.txt' in the current directory. By clicking the 'save-here'-button you can chose, where to save the used formula. Clicking the 'open'-button leads directly to the file where the formula was saved in.\n\nIf LaTex is selected, the formula is also written to the .txt file. You can copy this into a .tex document. If you import there the 'amsmath' module (\\usepackage{amsmath}), you can use this formula without editing.\n\n## Input and Result Examples\n\n### General Inpus\n| variable | value | error | formula | result |\n| ------ | ------ | ------ | ------ | ------ |\n| V, T, n | 2, 283.5, 4.3 | 0, 0.5, 0.03 | (n\\*8.314\\*T)/V | 5067.591+/-36.467 |\n| x | 4.3 | 1.1 | sin(x)*3.5 | -3.2066+/-1.5431 |\n| y | 3.254 | 0.032 | log10(y) | 0.5124175+/-0,0042709 |\n| x, y | 4.3, 3.254 | 1.1, 0.032 | log(x)\\*\\*y | 3.4156+/-1.9497 |\n\n### Arithmetic Characters\n| characters and operators | meaning |  example |\n| ----- | ----- | ----- |\n| + | plus | 4+2=6 |\n| - | minus | 4-2=2 |\n| \\* | multiplication | 4\\*2=8 |\n| / | division | 4/2=2 |\n| \\*\\* | exponent | 4\\*\\*2=16 |\n| sqrt(x) | square root | sqrt(4)=2 |\n| log(x) | natural logarithm | log(2.71828)=1 |\n| logY(x) | logarithm with base Y | log10(2.71828)=0.4343 |\n| sin(x) | sinus in radian | sin(1)=0.8415 |\n| cos(x) | cosinus in radian | cos(1)=0.5403 |\n| tan(x) | tangens in radian | tan(1)=1.5574 |\n| asin(x) | arcsinus in radian | asin(1)=1.5707 |\n| acos(x) | arccosinus in radian | acos(1)=0 |\n| atan(x) | arctangens in radian | atan(1)=0.7854 |\n| exp(x) | exponentialfunktion of e^(x) | exp(2)=7.3891 |\n\n\n\n## Requirements\n- Python >= 3.4\n- uncertainties\n- PyQt5\n\n## Installation\nerrorcalcs can be installed by `pip3 install errorcalcs` (Linux) or simply `pip install errorcalcs` (Windows). You can run the GUI with following code:\n\n\tfrom errorcalcs.errorcalcs import run\\_e\\_c\n\trun\\_e\\_c()\n\n\n",
