<dt><em>Description</em>:<dd><code>ANINT(A [, KIND])</code> rounds its argument to the nearest whole number.
<br><dt><em>Standard</em>:<dd>Fortran 77 and later
<br><dt><em>Class</em>:<dd>Elemental function
<br><dt><em>Syntax</em>:<dd><code>RESULT = ANINT(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 of the argument 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 real with the kind type parameter of the
argument if the optional <var>KIND</var> is absent; otherwise, the kind
type parameter will be given by <var>KIND</var>. If <var>A</var> is greater than
zero, <code>ANINT(A)</code> returns <code>AINT(X+0.5)</code>. If <var>A</var> is
less than or equal to zero then it returns <code>AINT(X-0.5)</code>.
<br><dt><em>Example</em>:<dd>
<pre class="smallexample"> program test_anint
real(4) x4
real(8) x8
x4 = 1.234E0_4
x8 = 4.321_8
print *, anint(x4), dnint(x8)
x8 = anint(x4,8)
