precision
Comp-3 -- Packed Decimal Number of bytes is

Answer / cauvitha

comp - used for binary representation. To make the calculations faster. it can have S and 9.
Memory usage is
s9(1)-s9(4) - 2bytes

s9(10)-s9(18) - 8bytes

===

comp-3 - used to store packed decimal values. Stores comparitively more values than comp. It can have S, 9, V.
