<p>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.
|
||
|
|
</p>
|
||
|
|
<p>The standard SRFI-4 procedures and data types may be included via loading the
|
||
|
|
appropriate module:
|
||
|
|
</p>
|
||
|
|
<div class="example">
|
||
|
|
<pre class="example-preformatted">(use-modules (srfi srfi-4))
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>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!)
|
||
