NAME

       Tcl_PrintDouble - Convert floating value to string

SYNOPSIS

       #include <tcl.h>

       Tcl_PrintDouble(interp, value, dst)

ARGUMENTS

       Tcl_Interp   *interp   (in)      Before   Tcl   8.0,  the  tcl_precision  variable  in  this  interpreter 2
                                        controlled the conversion.  As of Tcl 8.0, this argument is ignored  and 2
                                        the  conversion  is controlled by the tcl_precision variable that is now 2
                                        shared by all interpreters.

       double       value     (in)      Floating-point value to be converted.

       char         *dst      (out)     Where  to  store  string  representing  value.   Must  have   at   least
                                        TCL_DOUBLE_SPACE characters of storage.

DESCRIPTION

       Tcl_PrintDouble  generates  a  string  that  represents the value of value and stores it in memory at the
       location given by dst.  It uses %g format to generate the string, with one special twist: the  string  is
       guaranteed to contain either a ``.'' or an ``e'' so that it doesn't look like an integer.  Where %g would
       generate an integer with no decimal point, Tcl_PrintDouble adds ``.0''.
