    <para>
     Compares the <parameter>left_operand</parameter> to the
     <parameter>right_operand</parameter> and returns the result as an
     integer.  The optional <parameter>scale</parameter> parameter is
     used to set the number of digits after the decimal place which
     will be used in the comparison.  The return value is 0 if the two
     operands are equal.  If the <parameter>left_operand</parameter>
     is larger than the <parameter>right_operand</parameter> the
     return value is +1 and if the <parameter>left_operand</parameter>
     is less than the <parameter>right_operand</parameter> the return
     value is -1.
