I noticed that the Serial.print statement does not support uint64_t variables. This has me wondering if the math package supports 64 bit calculations. I wonder if anyone here can enlighten me?

Thanks in advance for any help!

I don't understand your question ...
Serial.print() is character based function.
Why it should be aware of uint64_t ?
Post your guilty code so that we can figure out ...

Thanks for your interest!

I understand Serial.println() prints ASCII characters but it automatically does the conversion for uint32_t, 32 bit integers. Since my post I noticed a posting of an alternate println library function that apparently will handle 64 bit integers.

You have me thinking that I should try an itoa conversion to a char array and then print the result. I am not sure if the itoa function works for 64 bit integers - possibly that is the problem.

BTW I would like to delete my other similar post under general discussions but do not know how to do that.

Thanks again!

But about your original question about uint64_t, did it failed to compile or not ?
