Clean looking engineering calculations for IPython

ipycalc

Simple Engineering Calculations in Python

Turn the contents of a Jupyter cell into a formatted calculation by following the steps below:

1. Install ipycalc using pip install ipycalc
2. Use from ipycalc import calc to bring ipycalc into your notebook's namespace.
3. Use %%calc as the first line of a cell to indicate that you want to run ipycalc on the contents of a cell.

The basic calculation syntax is:

Variable Description: variable_name = python_expression -> result_decimal_places*result_unit # Reference Text

Key components of the ipycalc syntax are:

• : (required) The description must come before this character.
• = (optional) Used to assign a python expression to a variable name. Omit this if you simply want to reprint a previously defined variable.
• -> (optional) Separates the python expression from the results formatting rules.
• * (optional) Indicate the number of decimals you want to see in the result to the left of the *, and the units you want to see in the result to the right.
• # (optional) Indicates reference text to the side of the calculation - handy for equation references or code references.

Here are a few useful things to keep in mind when using ipycalc:

• Subscripts can be added by using the _ character to indicate the start of a subscript.
• To stack fractions place the numerator and denominater in parentheses: (num)/(denom) yields $\dfrac{num}{denom}$.
• If statements and else statements are available using python's inline if statement notation.
• Square roots can be displayed using sqrt.
• Prime characters can be displayed using ^prime.
• If a line gets too long for printing, you can add a line break to the description, equation, or reference by inserting \\.
• ipycalc assists you with printing your notebooks. It has a built in nbconvert template called ipycalc that works just like the webpdf template, except it fixes the the bad margins in the webpdf template, and avoids page breaks right after headers. Any cells tagged with hide_cell will not be rendered. Any cells tagged with hide_input will only show the output upon printing. You can select it from the file menu via "File -> Save and Export Notebook As... -> Ipycalc"

IPycalc is still in its infancy. I'm sure there are bugs, so be cautious and use your head. A special thanks to @connorferster for handcalcs which inspired this project: https://github.com/connorferster/handcalcs
