  26. Usage        char *gcvt(double value, int ndec, char *bufP);
  27.  
  28. Prototype in    stdlib.h

  30. Description    gcvt converts  value to a  null-terminated ASCII string  in
  31.         bufP and returns a pointer  to bufP. It attempts to produce
  32.         ndec  significant digits  in FORTRAN  F-format if possible;
  33.         otherwise,  E-format  (ready  for  printing)  is  returned.
  34.         Trailing zeros may be suppressed.
  35.  
  36. Return value    gcvt returns the string pointed to by bufP.
