34 | <p>The keyword <b><font face="Courier New">integer</font></b> denotes a simple basic type whose distinguished values are the positive and negative whole numbers, including zero.</p> | |
35 | <ul> | |
36 | <li>Values of integer type shall be <a href="#double_quotation">denoted by one or more digits</a>; the first digit shall not be zero unless the value is 0.</li> | |
37 | <li>The value zero shall be represented by a single zero.</li> | |
38 | <li>The <a href="#quotation_inside">range of the permitted integer values</a> may be specified.</li> | |
39 | <li>The specified <a href="infinity.html#double_quotation">range may be infinite</a> (both positive and negative; see the keyword <a href="infinity.html"><b><font | |
40 | face="Courier New" color="#003258" size="4">infinity</font></b></a>).</li> | |
41 | <li>Another way to limit the permitted integer values is <a href="#list">to list them</a>.</li> | |
42 | <li>Value list and value range restrictions <a href="#relation">may be combined</a></li> | |
43 | <li>Predefined function operating on integer numbers:</li> | |
