+The math intrinsics required by the 1977 Fortran standard are
+available, although not described here.  In addition, the
+\fIabs\fP, \fIsqrt\fP, \fIexp\fP, \fIlog\fP, \fIsin\fP, and \fIcos\fP 
+intrinsics have been extended for double complex values.
+They may be referenced using the generic names listed above,
+or they may be referenced using their specific names that
+consist of the generic names preceded by either \fIcd\fP or
+\fIz\fP.  For example, if \fIzz\fP is double complex, then
+\fIsqrt(zz)\fP, \fIzsqrt(zz)\fP, or \fIcdsqrt(zz)\fP compute
+the square root of \fIzz\fP.  The \fIdcmplx\fP intrinsic
+forms a double complex value from two double precision variables
+or expressions, and the name of the specific function for the conjugate
+of a double complex value is \fIdconjg\fP.

 Most of these functions are in libU77.a. 
 Some are in libF77.a or libI77.a.
 A few intrinsic functions are described for the sake of completeness.
