| <dt><em>Description</em>:<dd><code>NINT(A)</code> rounds its argument to the nearest whole number. |
| |
| <br><dt><em>Standard</em>:<dd>Fortran 77 and later, with <var>KIND</var> argument Fortran 90 and later |
| |
| <br><dt><em>Class</em>:<dd>Elemental function |

| expression indicating the kind parameter of the result. |
| <br></td></tr></table> |
| |
| <br><dt><em>Return value</em>:<dd>Returns <var>A</var> with the fractional portion of its magnitude eliminated by |
| rounding to the nearest whole number and with its sign preserved, |
| converted to an <code>INTEGER</code> of the default kind. |
