    Welcome to AAC, shaider530,

    I have moved your thread into the more appropriate "math" forum.

    tried it on my calculator :p
    got a math error which is the same error for an operation involving division by zero.
    perhaps it is an invalid operation.u get the same error for anything(including real number) raised to i.

    Try
    Code ( (Unknown Language)):
    1.  
    2. exp( j*ln(j)) = 0.20788
    3.  
    4. ln(j) = (j*pi)/2
    5. j*ln(j) = (j²*pi)/2 = -pi/2
    6. exp(-pi/2) = 0.20788
    7.  
    This all comes from Euler's equation that

    Code ( (Unknown Language)):
    1.  
    2. exp(i*pi) = -1
    3.  
    My TI-92 also gives that result without any sort of complaint.
