Approximate value of π²/6
nekketsuuu opened this issue · comments
In this line of the tutorial, we calculate an approximate value of (/ (power pi 2) 6).
But we can't show the real value of (/ (power pi 2) 6) in Egison because pi is defined as a symbol π and because it seems that Egison doesn't have f.power currently.
Proposal: Therefore, how about adding a description how to calculate the real value? For example, we can calculate the value by (f./ (f.* f.pi f.pi) 6.0).
Thank you for adding the issue!
Yes, (/ (power pi 2) 6) was executable only by the past version of Egison.
I updated this expression to (f./ (f.* f.pi f.pi) 6.0) as your proposal.
