NAME
     Tcl_PrintDouble - Convert floating value to string

SYNOPSIS
     #include 

     Tcl_PrintDouble(interp, value, dst)

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

     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''.
