| <dt><em>Description</em>:<dd><code>FLOOR(A)</code> returns the greatest integer less than or equal to <var>X</var>. |
| |
| <br><dt><em>Standard</em>:<dd>Fortran 95 and later |
| |
| <br><dt><em>Class</em>:<dd>Elemental function |
| |
| <br><dt><em>Syntax</em>:<dd><code>RESULT = FLOOR(A [, KIND])</code> |
| |
| <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%">The type shall be <code>REAL</code>. |
| <br></td></tr><tr align="left"><td valign="top" width="15%"><var>KIND</var> </td><td valign="top" width="70%">(Optional) An <code>INTEGER</code> initialization |
| expression indicating the kind parameter of the result. |
| <br></td></tr></table> |
| |
| <br><dt><em>Return value</em>:<dd>The return value is of type <code>INTEGER(KIND)</code> if <var>KIND</var> is present |
| and of default-kind <code>INTEGER</code> otherwise. |
| |
| <br><dt><em>Example</em>:<dd> |
| <pre class="smallexample"> program test_floor |
| real :: x = 63.29 |
| real :: y = -63.59 |
| print *, floor(x) ! returns 63 |
