Hi,
so it's given that s = 1 − 1/3 + 1/5 − 1/7 + 1/9 − 1/11 + · · · + (−1)^n / (2n + 1)
what I need to do is, with a while-loop, see after how many terms (n) the equation above gives the same 5 first decimals as pi/4, which is 0.78539...
p = 0;
i = 0;
while 1 == 1 % Infinite loop
p = p + ((-1)^i)/(2*i + 1);
i = i + 1;
if
break
end
end
I just don't really know what to write in the if statement, tried so much but nothing is really working, would appreciate some help -_-

if abs(p - pi/4) < 1e-5
Look through the tag floating-point to know why tolerance is used to compare decimals.
