+Singular's arbitrary precision arithmetic can be realized using the
+GNU multiple precision library, or the smallgmp library contained in
+this distribution, or using Singular build-in routines. Using the GNU
+multiple precision (GMP) library results in the best performance. The
+smallgmp library contained in this distribution is a subset of GMP
+which is written in C, only. Its performance is usually not quite as
+good as that of the original gmp library. Singular's build-in
+arbitrary precision routines are the least efficient.
