Improving FIX mode

[Pyjam]

It took me a while to figure it out too.
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 2, it can go down to 0.0nn, and in FIX 4 to 0.00nn, and so on.
In FIX 3 and DIG 3, it can go down to 0.nnn, and in FIX 4 to 0.0nnn, and so on.
I'd find it normal to choose DIG = FIX. But it’s far from being a true FIX mode.

I think the real problem is that some users want a non-SCI display for numbers that aren't too large, because they want to read 12.36 rather than 1.236 E+01. And they want to switch to SCI or ENG for large or really small numbers. It's the SIG mode they really want, as I've described here:

I don't know if this display format exists on DB48.
