For integers %nd prints with n characters and uses leading spaces.
If you want leading zeros then use %0nd where n is the total characters
So %02d should do what you want.

Ah - thank you!
Yes, that does work, albeit not to the c/c++ standard
I see souces in the ESP directories using the correct '%.' specifier, so somethings broke ...

The %02d is OK in C, C++ The first character after the % can be a flag
nothing = pad with spaces
- left justify
+ display sign
0 pad with zeros
See
https://en.wikipedia.org/wiki/Printf_format_stringThe main arduino printf implementation has been weak for floating point which I guess is why the precision . version is problematic.
