  2. *cvt.h - definitions used by formatting routines
  3. *
  4. * Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
  5. *
  6. *Purpose:
  7. * cvt.h contains definitions used by the formatting routines [efg]cvt and
  8. * _output and _input. The value of CVTBUFSIZE is used to dimension
  9. * arrays used to hold the maximum size double precision number plus some
  10. * slop to aid in formatting.
  11. *
  12. * [Internal]
  13. *
  14. *Revision History:
  15. * 12-11-87 JCR Added "_loadds" functionality
  16. * 02-10-88 JCR Cleaned up white space
  17. * 07-28-89 GJF Fixed copyright
  18. * 10-30-89 GJF Fixed copyright (again)
  19. * 02-28-90 GJF Added #ifndef _INC_CVT stuff. Also, removed some
  20. * (now) useless preprocessor directives.
  21. * 02-14-95 CFW Clean up Mac merge.
  22. * 03-29-95 CFW Add error message to internal headers.
  23. * 06-23-95 GJF Added leading '_' to several macros to avoid conflict
  24. * with macros in win*.h.
  25. * 12-14-95 JWM Add "#pragma once".
  26. * 02-24-97 GJF Detab-ed.
