function ret = mpfr_eint (rop, op, rnd)
% ret = mpfr_eint (rop, op, rnd)
%
% Set ROP to the exponential integral of OP, rounded in the direction
% RND.  This is the sum of Euler's constant, of the logarithm of the
% absolute value of OP, and of the sum for k from 1 to infinity of OP
% to the power k, divided by k and the factorial of k.  For positive
% OP, it corresponds to the Ei function at OP (see formula 5.1.10
% from the Handbook of Mathematical Functions from Abramowitz and
% Stegun), and for negative OP, to the opposite of the E1 function
% (sometimes called eint1) at −OP (formula 5.1.1 from the same
% reference).
