ECVT(S)                  XENIX System V                   ECVT(S)



     Name
          ecvt, fcvt, gcvt - Performs output conversions.

     Syntax
          char *ecvt (value, ndigit, decpt, sign)
          double value;
          int ndigit, *decpt, *sign;

          char *fcvt (value, ndigit, decpt, sign)
          double value;
          int ndigit, *decpt, *sign;

          char *gcvt (value, ndigit, buf)
          double value;
          int ndigit;
          char *buf;

     Description
          ecvt converts the value to a null-terminated string of
          ndigit ASCII digits and returns a pointer to the string.
          The position of the decimal point relative to the beginning
          of the string is stored indirectly through decpt (negative
          means to the left of the returned digits).  If the sign of
          the result is negative, the word pointed to by sign is
          nonzero, otherwise it is zero.  The low-order digit is
          rounded.

          fcvt is identical to ecvt, except that the correct digit has
          been rounded for FORTRAN F format output of the number of
          digits specified by ndigits.

          gcvt converts the value to a null-terminated ASCII string in
          buf and returns a pointer to buf.  It attempts to produce
          ndigit significant digits in FORTRAN F format if possible,
          otherwise E format, ready for printing.  Trailing zeros may
          be suppressed.

     Notes
          The return values point to static data whose content is
          overwritten by each call.
