millis() output

Hello,

I was trying to look at what a millis() time stamp looks like when millis() is call and fills a unsigned long with a time stamp. Does anyone know, or can anyone show, what the output for millis() looks like?

How many significant figures does it show? What's the format?

000000.000000? 0000.0000? 000000.00?

Been trying to google this to no avail. Still searching as you read.

Thank you

Unsigned long is 32 bits 0 to 4,294,967,295 (2^32 - 1).

What's the format?

All of your formats suggest that millis() returns a float. It doesn't take 60 seconds to look at the documentation, or 2 minutes to look at the source code, to see what it actually returns.

How many significant figures does it show? What's the format? 000000.000000? 0000.0000? 000000.00?

6, 4 and 2 significant digits.

This is how display formatting works in LabVIEW (with description).

millis() returns the INTEGER number of milliseconds since restart...
