Calculate Pasted Values in Python by pasting the values into a string array and calculating; this is a personal utility for python environments, not to be called as a script as it has no meaningful input options

PasteCalc

PasteCalc is a personal utility for Python environments that allows you to calculate values by pasting them into a string array. This utility is not meant to be called as a script as it does not have meaningful input options.

Getting Started

To use this script, follow the instructions below:

1. Ensure you have Python installed on your system.
2. Install the mpmath library by running the command: pip install mpmath.
3. Setup a Python3 environment or use a Python based notebook (you may also call the script, but the values will have to be edited in the script every time)

Usage

1. Open the script in a Python editor or IDE.

2. Modify the input parameters as needed:

   • v: Paste the values you want to use for calculations between the specified lines.
   • number: Set the initial number for calculations. If set to 0, the script will use the first value from the v list.
   • operation: Choose the operation to perform:
     • 0: Addition
     • 1: Subtraction
     • 2: Multiplication
     • 3: Division
   • precision: Adjust the precision of the calculations (optional).
   • print_iterations: Set to True to print the result after each iteration.
   • output_option: Choose the output option:
     • 0: Partial scientific notation
     • 1: Full result
     • 2: Save to file
     • 3: Partial truncated result

3. Run the script. The calculated result will be displayed based on the chosen output option.

Note: If you choose output option 2 (save to file), the result will be saved in a file named calcd.txt.

Usage

1. Open the PasteCalc.py script in a Python editor or IDE.
2. Copy the values you want to calculate.
3. Replace the placeholder lines in the string in the v variable with the copied values.
4. Run the script. No need to format, no need to add a tab, no need to add a comma at the end.

The calculated result will be displayed based on the specified operation and output options.

Output Options:

---  (X, True, True, True) 
A number indicating the style of the output:
-1 = full rounded down outputs,
 0 = partial scientific (displays 10 digits),
 1 = full rounded up outputs,
 2 = full output, no scientific notation, as many decimals as dps + precision are set to,
 3 = partial truncated (truncates all but 100 digits).

--- (0, X, True, True) 
A boolean indicating whether the result should be saved to a file.

--- (0, True, X, True) 
A boolean indicating whether the result of each iteration should be
printed or saved to a file (based on the value of the second boolean
in the tuple).

--- (0, True, True, X) 
A boolean if set to True will show the equation
