<dt><em>Description</em>:</dt>
|
|
<dd><p><code>LSHIFT</code> returns a value corresponding to <var>I</var> with all of the
|
|
bits shifted left by <var>SHIFT</var> places. If the absolute value of
|
|
<var>SHIFT</var> is greater than <code>BIT_SIZE(I)</code>, the value is undefined.
|
|
Bits shifted out from the left end are lost; zeros are shifted in from
|
|
the opposite end.

|
<p>This function has been superseded by the <code>ISHFT</code> intrinsic, which
|
|
is standard in Fortran 95 and later, and the <code>SHIFTL</code> intrinsic,
|
|
which is standard in Fortran 2008 and later.
