@momba98, thanks for that. This also brings up rendering of arrays (numpy arrays work but not list yet). This needs doing.

I have been thinking about sum for a while: as I understand, sigma notation typically describes the series in general but in this instance, we would just be rendering something like: \Sigma (1, 2, 3). Is this how you would expect to see that, with the numbers of the array in parentheses separated by , ?

I believe it will be implemented soon. As far as I know, only basics functions are rendered, like sqrt and integrate.

I tried to render Sigma (sum) by sum() builtin function too, but I was unsucessful.

Hi @jm4rc05,

Thanks for mentioning those. I had to Google ceiling notation just now: I did not know that ceil had special notation! However, the current ceil notation is indeed using the Latex \ceil function which I understand is also considered proper notation, is that correct? Besides the L-shaped brackets, there anything else to the ceil notation? Please tell me more about this.

The log function is also using the \log Latex function. However, I do not currently do any thing to read the parameters of the log function to make it like log_a b or to change log to \ln when it is on base e. I will implement that!

Yep. That is what I thought. In #long, probably we would see \Sigma (name of the array) and then after \Sigma (numbers of the array). That would be awesome to comprehend calculation logic.

Another point I imagine is crucial is matrix operations. It would be outstanding to be visualizing these operations. In my opinion, it is one of the hardest to see out of the paper.

Thanks for asking!

This is coming in the next release (ceil, log, sum). Likely this week.

Matrices and dataframes are tricky. New ideas are needed. See here: https://github.com/connorferster/handcalcs/wiki/Handcalcs-with-pandas-and-numpy

@jm4rc05 btw, in the picture that notation is actually for the floor function not the ceil function. The ceil function is vertically inverted L.

@jm4rc05 This has now been implemented in the latest v1.1.0 release.
