  8. The <b>BOOST_PP_EQUAL_D</b> macro compares two values for equality.
  9. </div>
  10. <h4>Usage</h4>
  11. <div class="code">
  12. <b>BOOST_PP_EQUAL_D</b>(<i>d</i>, <i>x</i>, <i>y</i>)
  13. </div>
  14. <h4>Arguments</h4>
  15. <dl>
  16. <dt>d</dt>
  17. <dd>
  18. This argument is ignored.
  19. </dd>
  20. <dt>x</dt>
  21. <dd>
  22. The left operand of the comparison.&nbsp;
  23. Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
  24. </dd>
  25. <dt>y</dt>
  26. <dd>
  27. The right operand of the comparison.&nbsp;
  28. Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
  29. </dd>
  30. </dl>
  31. <h4>Remarks</h4>
  32. <div>
  33. If <i>x</i> is equal to <i>y</i>, this macro expands to <i>1</i>.&nbsp;
  34. Otherwise, it expands to <i>0</i>.
  35. </div>
  36. <div>
  37. This macro is deprecated.&nbsp;
  38. It only exists for backward compatibility.&nbsp;
  39. Use <b>BOOST_PP_EQUAL</b> instead.
