| <br><dt><em>Arguments</em>:<dd> |
| <p><table summary=""><tr align="left"><td valign="top" width="15%"><var>A</var> </td><td valign="top" width="70%">Shall be of type <code>INTEGER</code>, |

| <br><dt><em>Return value</em>:<dd>These functions return a <code>INTEGER</code> variable or array under |
| the following rules: |
| |
| <dl> |
| <dt>(A)<dd>If <var>A</var> is of type <code>INTEGER</code>, <code>INT(A) = A</code> |
| <br><dt>(B)<dd>If <var>A</var> is of type <code>REAL</code> and |A| < 1, <code>INT(A)</code> equals <code>0</code>. |
| If |A| \geq 1, then <code>INT(A)</code> equals the largest integer that does not exceed |
| the range of <var>A</var> and whose sign is the same as the sign of <var>A</var>. |
| <br><dt>(C)<dd>If <var>A</var> is of type <code>COMPLEX</code>, rule B is applied to the real part of <var>A</var>. |
