uint32_t ceil_log10_pow2 (uint32_t e)
```
Returns 1 + floor(log_10(2^e). This could technically be off by 1 if any

power of 2 was also a power of 10, but since that doesn't exist this is

always accurate. This is used to calculate the maximum number of base-10

digits a given e-bit number could have.

UInt<MID_INT_SIZE> get_table_negative (int exponent, size_t i)
```
The formula for the table when i is negative (or zero) is as follows:

floor(10^(-9i) * 2^(c_0 - e)) % (10^9 * 2^c_0)

Since we know i is always negative, we just take it as unsigned and treat it

as negative. We do the same with exponent, while they're both always negative

in theory, in practice they're converted to positive for simpler

calculations.

The formula being used looks more like this:

floor(10^(9*(-i)) * 2^(c_0 + (-e))) % (10^9 * 2^c_0)
