Tcl_PrintDouble - Convert floating value to string
Tcl_PrintDouble(interp, value, dst)
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
conversion, double-precision, floating-point, string
- 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 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.
