     EXP, DEXP, CEXP, and CDEXP return e**gen.
 
     LOG, ALOG, DLOG, CLOG, and CDLOG return the natural logarithm of
     their respective arguments. LOG10, ALOG10, and DLOG10 return the
     base-10 logarithm of their arguments.
 
     For all logarithmic functions, real arguments must be greater than
     zero. The CLOG and CDLOG functions return the logarithm of a
     complex number. The real component is the natural logarithm of the
     magnitude of the complex number. The imaginary component is the
     principal value of the angle of the complex number, in radians.
