/* Arithmetic Precision
 *
 * The precision of the arithmetic used by Sparse can be set by
 * changing changing the spREAL macro.  This macro is
 * contained in the file spMatrix.h.  It is strongly suggested to
 * used double precision with circuit simulators.  Note that
 * because C always performs arithmetic operations in double
 * precision, the only benefit to using single precision is that
 * less storage is required.  There is often a noticeable speed
 * penalty when using single precision.  Sparse internally refers
 * to a spREAL as a RealNumber.
