Tcl_PrintDouble − Convert floating value to string
#include <tcl.h>
Tcl_PrintDouble(interp, value, dst)
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. |
_________________________________________________________________
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’’.
