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 argu |
ment 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_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 format to generate the string,
with one special twist: the string is guaranteed to con
tain 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''.
