These operators accept plain or long integers as arguments. The
arguments are converted to a common type. They shift the first
argument to the left or right by the number of bits given by the
A right shift by
<var>n
</var> bits is defined as division by
<code>pow(
2,
<var>n
</var>)
</code>. A left shift by
<var>n
</var> bits is defined as
multiplication with
<code>pow(
2,
<var>n
</var>)
</code>; for plain integers there is
no overflow check so in that case the operation drops bits and flips
the sign if the result is not less than
<code>pow(
2,
31)
</code> in absolute
value. Negative shift counts raise a
