Here's the abstract:

  This SRFI describes a set of datatypes for vectors whose
  elements are of the same numeric type (signed or unsigned exact
  integer or inexact number of a given precision).  These
  datatypes support operations analogous to the Scheme vector
  type, but they are distinct datatypes.  An external
  representation is specified which may be supported by the read
  and write procedures and by the program parser (i.e. programs
  can contain references to literal homogeneous vectors).

Regards,

SRFI Editor
