DIG is the minimum number of significant digits you want to see, otherwise it goes to SCI.
In FIX 3 and DIG 1, it can go down to 0.00n, and in FIX 4 to 0.000n, and so on.

In Fix 3 and Dig 0, it can go down to 0.00n too!

What is 0 significant digit? It is just too confusing.

From https://github.com/c3d/DB48X-on-DM42/iss...1765870801
Fix 4 and Dig 0: 0.000055 --> 0.0001
Fix 4 and Dig 1: 0.000055 --> 5.5000e-5

at least one real significant digit to show, and the 1 there is not significant (it’s rounding)

What is real significant digit? Round up from 0 to 1 not real?

Even without rounding up, 0 is a significant digit.

to indicate its presence it is usually considered to have a precision of 1.
