Synopsis:
    #include <stdlib.h>
    char *fcvt( double value,
                int ndigits,
                int *dec,
                int *sign );

Description:
    The fcvt function converts the floating-point number value into a
    character string.  The parameter ndigits specifies the number of digits
    desired after the decimal point.  The converted number will be rounded
    to this position.

    The character string will contain only digits and is terminated by a
    null character.  The integer pointed to by dec will be filled in with a
    value indicating the position of the decimal point relative to the start
    of the string of digits.  A zero or negative value indicates that the
    decimal point lies to the left of the first digit.  The integer pointed
    to by sign will contain 0 if the number is positive, and non-zero if the
    number is negative.

Returns:
    The fcvt function returns a pointer to a static buffer containing the
    converted string of digits.  Note:   ecvt and  fcvt both use the same
    static buffer.

Example:
    #include <stdio.h>
    #include <stdlib.h>

    void main()
      {
         char *str;
         int  dec, sign;

         str = fcvt( -123.456789, 5, &dec, &sign );
         printf( "str=%s, dec=%d, sign=%d\n", str,dec,sign );
      }

    produces the following:

    str=12345679, dec=3, sign=-1
