Pi is a reserved work, so I used pie. I haven’t seen this way of producing Pi before, and in both JavaScript and LivceCode it seems to be instantaneous. I think it’s a rewording of 4*(1-1/3+1/5-1/7+1/9…)
Anyway, see for yourself
on mouseup
put the ticks into t
put 1.0 into i
put 3.0 * 10^200 into x
put x into pie
repeat while (x > 0)
put x * i / ((i + 1.0) * 4.0) into x
add x / (i + 2.0) to pie
add 2.0 to i
end repeat
set numberformat to "x.xxxxxxxxxxxxxxxxxxxxxxx"
answer the ticks - t
answer (pie / (10.0 ^ 200))
end mouseup
BTW, I haven’t seen JavaScript using ‘let’ before, or having ’n’ to indicate a floating point number. That could be a dot net thing.
