        !            22: .it Ecvt
        !            23: is called with a floating point number in fr0.
        !            24: .s3
        !            25: On exit, the number has been converted into a
        !            26: string of ascii digits in a buffer pointed to by r0.
        !            27: The number of digits produced is controlled
        !            28: by a global variable \fI\*_ndigits\fR.
        !            29: .s3
        !            30: Moreover, the position of the decimal point is
        !            31: contained in r2: r2=0 means the d.p. is at the
        !            32: left hand end of the string of digits;
        !            33: r2>0 means the d.p. is within or to the right
        !            34: of the string.
        !            35: .s3
        !            36: The sign of the number is indicated by r1 (0 for +; 1 for \*-).
        !            37: .s3
        !            38: The low order digit has suffered decimal rounding
        !            39: (i. e. may have been carried into).
        !            40: .s3
        !            41: From C,
        !            42: the
        !            43: .it value
        !            44: is converted and a pointer to a null-terminated
        !            45: string of \fIndigit\fR digits is returned.
        !            46: The position of the decimal point is stored indirectly
        !            47: through \fIdecpt\fR (negative means to the left of the
        !            48: returned digits).
        !            49: If the sign of the result is negative,
        !            50: the word pointed to by \fIsign\fR is non-zero, otherwise
        !            51: it is zero.
        !            52: .s3
        !            53: \fIFcvt\fR is identical to \fIecvt\fR, except that the correct digit
        !            54: has had decimal rounding for F-style output of the number
        !            55: of digits specified by \fI\(*_ndigits\fR.
