    ECVT(3)             UNIX Programmer's Manual		  ECVT(3)

    NAME
         ecvt, fcvt, gcvt - output conversion

    SYNOPSIS
         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;
         char *buf;

    DESCRIPTION
         Ecvt converts the value to a null-terminated string of ndi-
         git ASCII digits and returns a pointer thereto.  The posi-
         tion 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 non-zero, other-
         wise 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.

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