Tcl_PrintDouble(3)	    Tcl Library Procedures	    Tcl_PrintDouble(3)

______________________________________________________________________________

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	  con- |
					trolled	 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 interpreters.

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

       char	    *dst      (out)	Where  to  store  string  representing
					value.	 Must  have  at least TCL_DOU-
					BLE_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 for-
       mat to generate the string, with one special twist: the string is guar-
       anteed  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''.

KEYWORDS
