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 the 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 does not look like
       an  integer.  Where %g would generate an integer with no decimal point,
       Tcl_PrintDouble adds “.0”.					       │

       If the tcl_precision value is non-zero, the result will have  precisely │
       that  many digits of significance.  If the value is zero (the default), │
       the result will have the fewest digits needed to represent  the	number │
       in  such a way that Tcl_NewDoubleObj will generate the same number when │
       presented with the given string.	 IEEE semantics of  rounding  to  even │
       apply to the conversion.
