closes #1711

Needs #1870 to work

Current status: Both SignedDecimal and SignedDecimal256 are finished

I added negative cases to almost all tests
I had to adjust these methods (compared to Decimal): from_str, saturating_{add, sub, mul, pow}, to_int_{floor, ceil}
I added some new methods: trunc and to_int_trunc
I removed sqrt, as we don't have it for the signed ints atm and it would have to return a Result in case of negative numbers

Adding this to 1.4 for visibility, but would not consider it a hard release blocker. If we can get it in, great.

webmaster128 modified the milestones: 1.4.0, 2.0.0

Looks very good

I removed sqrt, as we don't have it for the signed ints atm and it would have to return a Result in case of negative numbers

I think it's fine to not have that. Square root of negative numbers only work in complex math. I think users can be asked to convert to unsigned first and ensure errors are handles in that step.
