    Cleanups for psi and bug fix for exp-integral-e. · 19dd5231
    Raymond Toy authored
    * Allow (exp-integral-e 1 z) to work.
    * psi
      * Handle psi(1) specially.
      * Do a better job with cot(%pi*z) when z is an odd multiple of 1/2
        where cot is 0.
      * Fib bug in computing the number of terms when we try to float a
        complex.  Just float the realpart.
