[Feature] abbreviate multi-million credit values

Is your feature request related to a problem? Please describe.
Once I'm looking at an unsold value of 158,209,100 Cr. a lot of those numbers stop being really meaningful. The difference between 159,209,000 and 159,208,100 Cr. is quite small.

The extra detail makes it harder to understand, at a glance, what my balance is. (For me; I'm sure others don't experience the same.)

Describe the solution you'd like
I'd prefer to see "up to four significant digits" of value. So, for example:

Value             Display
1,234             1,234 Cr.
12,345            12.34k Cr.
123,456           123.5k Cr.
1,234,567         1,234k Cr.
12,345,678        12.35m Cr.
123,456,789       123.5m Cr.
1,234,567,890     1,235m Cr.

Round to nearest (.0 - .499 => 0, .5 - .999 => 1) seems to work best with that.

Describe alternatives you've considered
Any shortening would be fine, really, if it kept to three or four digits. Even five is probably fine to take in quickly, at a glance.

Additional context
I've used this before in displaying numbers where quick reference, at a glance comprehension was needed. It was the best way I found to manage that; people "get" four numbers fast, without getting overwhelmed, but it still shows the "right" amount of detail for humans at each stage.

Currently have a version of this on dev using SI prefixes so far.

each consecutive line is x10 the previous one gives this

1 Cr.
10 Cr.
100 Cr.
1.000 KCr.
10.00 KCr.
100.0 KCr.
1.000 MCr.
10.00 MCr.
100.0 MCr.
1.000 GCr.
10.00 GCr.
100.0 GCr.
1.000 TCr.
10.00 TCr.
100.0 TCr.
1.000 PCr.
.
.
.

Probably should force myself and make an extra case where the decimal point is directy after the first digit to be a thousand seperator instead and use the lower SI prefix because I just realized 1.000 KCr. could be misinterpreted as being 1,000 KCr. while actually just being 1 KCr.
