# SRFI 4: Homogeneous numeric vector datatypes

by Marc Feeley

status: final (1999/5/22)

## 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 real 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 must be supported by the read and write procedures and by the program parser (i.e. programs can contain references to literal homogeneous vectors).
