c++ - How to print double using wsprintf -

-

i unable print double value using wsprintf(). tried sprintf() , worked fine.

syntax used wsprintf() , sprintf() follows:

wsprintf(str,text("square %lf "),isquare); // not show value  sprintf(str," square %lf",isquare);  // works okay

am making mistakes while using wsprintf() ?

wsprintf doesn't support floating point. mistake using @ all.

if want sprintf, wide characters/strings, want swprintf instead.

actually, since you're using text macro, want _stprintf instead though: it'll shift narrow wide implementation in sync same preprocessor macros text uses decide whether string narrow or wide.

for it's worth: wsprintf entirely historic relic. w apparently stands windows. included part of windows way when (back @ least windows 2.1, windows 1). written without support floating point because @ time, windows didn't use floating point internally (at all).
