The question about the type numeric

Hi hackers,

I am learning about numeric .
The comment of NumericShort format is:
* In the NumericShort format, the remaining 14 bits of the header word
* (n_short.n_header) are allocated as follows: 1 for sign (positive or
* negative), 6 for dynamic scale, and 7 for weight. In practice, most
* commonly-encountered values can be represented this way.

So the Max of the NumericShort format should be up to 508 digits before the decimal point.
So the sign of the number 12345678901234567890123456789012345678901234567890
12345678901234567890123456789012345678901234567890123456789012345678901234567890
12345678901234567890123456789012345678901234567890123456789012345678901234567890
12345678901234567890123456789012345678901234567
should be 0x807F.
The number is 257 digits before the decimal point.
But the sign is 0.
So is there anything wrong?

Thank you!
