MATLAB: How can i seperate the value exp(1i*2*pi*bbbb);

exponent

x1=exp(1i*2*pi*bbbb);
d1=bb1.*exp(1i*2*pi*bbbb);
d2=abs(d1);
d3=angle(d1);
d4=exp(1i*d3);   %value are not same as x1 
%how can i extract the value of x1 from d1

The question is unlcear.
Given d1 from [d1 = bb1 * exp(a)], are you asking how to get exp(a)? If so, 
exp(a) = log(d1/bb1);
