.002 is obvious - but not any amount a bank is going to be concerned about.
e is the base from a natural logarithm. i is the squareroot of -1 (used mainly in imaginary numbers and circuits). The numerical notation for i is (0,1)
Sigma is a summation. In this case - it is the summation from 1 to infinity of 1/(2^n) ... so that becomes 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64 etc to infinity (so you end up with a very small number).
so what you wind up with is .002 + e^((0,1)*3.14) + the summation
I don't have a calculator with me - but I'd bet the whole thing adds up to .01 or something very close to it.
