<p>The Basic Random Number Generation (CEERAN0) API generates a sequence of
|
|
uniform pseudorandom numbers between 0 and 1 using the multiplicative
|
|
congruential method with a user-specified seed.</p>
|
|
|
|
<br>
|
|
<!-- Please NOTE: DO NOT DELETE THIS SECTION if this API has no authorities and locks. -->
|
|
<!-- Instead, use the commented out coding below to indicate NONE. -->
|
|
<h3>Authorities and Locks</h3>
|
|
|
|
<!-- Use this if there are no authorities and locks. -->
|
|
<p>None.</p>
|
|

|
<br>
|
|
<h3>Required Parameter Group</h3>
|
|
|
|
<dl>
|
|
<dt><strong>seed (I/O)</strong></dt>
|
|
|
|
<dd>A 32-bit binary integer representing an initial value used to generate
|
|
random numbers. It must be a variable; that is, it cannot be an input-only
|
|
parameter. The valid range is 0 to 2 147 483 646.
|
|
|
|
<p>If the value of the seed parameter is 0, the seed is generated from the
|
|
current Greenwich Mean Time.</p>
|
|
|
|
<p>On return, CEERAN0 changes the value of <em>seed</em> so that it may be used
|
|
as the new seed in the next call.</p>
|
|
</dd>
|
|
|
|
<dt><strong>random_no (output)</strong></dt>
|
|
|
|
<dd>A 64-bit double floating-point pseudorandom number with a value between 0
|
|
and 1, exclusive. If <em>seed</em> is not valid, <em>random_no</em> is set to
|
|
-1 and CEERAN0 ends with a nonzero feedback code.</dd>
|
|
</dl>
|
|
|
|
<br>
|
|
<h3>Omissible Parameter</h3>
|
|
|
|
<dl>
|
|
<dt><strong>fc (output)</strong></dt>
|
|
|
|
<dd>A 12-byte feedback code passed by reference. If specified as an argument,
|
|
feedback information (a condition token) is returned to the calling procedure.
|
|
If not specified, and the requested operation was not successfully completed,
|
|
the condition is signaled to the condition manager.</dd>
|
|
