The BIGINT data type is an exact numeric data type: its accuracy is
preserved after arithmetic operations.
A BIGINT value requires 8 bytes of storage.
The range for signed BIGINT values is from ( -2e63) to ( +2e63
).
The range for unsigned BIGINT values is from 0 to ( 2e64 - 1 ).
By default, the data type is signed.

A decimal number with precision total digits and with scale of the digits
after the decimal point.
{ DECIMAL | DEC } [ ( precision [ , scale ] ) ]
The DECIMAL data type is an exact numeric data type; its accuracy is
preserved to the least significant digit after arithmetic operations.
The storage required for a decimal number can be estimated as:
2 + int( ( before+1 ) / 2 ) + int( ( after + 1 )/2 )
where int takes the integer portion of its argument, and before and after are
the number of significant digits before and after the decimal point. The
storage is based on the value being stored, not on the maximum precision
and scale allowed in the column.
precision An integer expression that specifies the number of digits in the
expression. The default setting is 30.
scale An integer expression that specifies the number of digits after the
decimal point. The default setting is 6.
The defaults can be changed by setting database options. For information,
see "PRECISION option" on page 205 and "SCALE option" on page 210.
