7.5.5 SRFI-4 - Homogeneous numeric vector datatypes

SRFI-4 provides an interface to uniform numeric vectors: vectors whose elements are all of a single numeric type. Guile offers uniform numeric vectors for signed and unsigned 8-bit, 16-bit, 32-bit, and 64-bit integers, two sizes of floating point values, and, as an extension to SRFI-4, complex floating-point numbers of these two sizes.

The standard SRFI-4 procedures and data types may be included via loading the appropriate module:

(use-modules (srfi srfi-4))

This module is currently a part of the default Guile environment, but it is a good practice to explicitly import the module. In the future, using SRFI-4 procedures without importing the SRFI-4 module will cause a deprecation message to be printed. (Of course, one may call the C functions at any time. Would that C had modules!)
