How can an integer be printed without sprintf

[MikeyMoMo]

I have tried 6 different ways. I am trying to avoid sprintf, if possible and have some kind of conversion in the single line of code.

Here's my last attempt of the 6 ways I tried:

ofr.printf(char*(timeinfo->tm_mday)); // timeinfo->tm_mday points to an integer.

gives this error:

C:\Arduino\@ESP32 Sketches\TTGO T4 v1.3\Triple_Time_on_T4_v1.3_Ver_12_MultiAC\Analog_Clock.ino: In function 'void showCorners(time_t)': Analog_Clock:183:14: error: expected primary-expression before 'char' ofr.printf(char*(timeinfo->tm_mday));

also tried:

ofr.printf(char(timeinfo->tm_mday));

and several others.

what does work:

strftime(charWork, sizeof(charWork), "%d", localtime(&now)); // Numeric day of month ofr.setCursor(0, tft.height() - 26); ofr.printf(charWork);

But that takes strftime or sprintf. Was trying for some kind of inline conversion like can be used practically everywhere else in ESP land.

Is the following not good enough?

ofr.printf("%d", timeinfo->tm_mday);

This was asked about a year ago. I mostly dropped this due to extreme slowness. I could not afford the time in time-critical functions. If I ever get back to try it for something, again, I will see what can be done. This was not an answer to the question, actually, but never mind, I don't really care much any more.
