<h2>Calling Math Bindable APIs</h2>
|
|
|
|
<p>ILE math bindable APIs can be called through the intrinsic functions of an
|
|
ILE language or through a call statement specific to the ILE language. In
|
|
either of the calling conventions, you need to specify one or two input
|
|
parameters for the math bindable API being called. The number of input
|
|
parameters is indicated in <a href="ile5a5.htm#TBLMATHTAB">Math API Descriptions</a> under
|
|
the No. Inputs column.</p>
|
|
|
|
<p>For example, if the number of input parameters for CEESxnnn is 1, the API is
|
|
based on the following format:</p>
|
|
|
|
<div class="box" style="width: 60%;">
