Hi All,
how is sign is stored in S9(17) comp-3 variable.
Answer with an Example will be of great help.
Answer Posted / viswanathan
Hi,
suppose s9(3)v9(4) comp 3 is the data type then
3+4 = 7 half bytes will be used for data.
the last half byte will be used for sign
in this example number of digits is odd(7).
so total size occupied will be 7/2 + 1/2 =4 bytes
first seven half bytes from left will have data part. so the
right most half byte will have sign value.
if this right most half byte value is D (1101) then it is -ve
if it is C (1100) or F (1111) then it is considered as +ve.
example 2
S9(4)v(2) comp 3
here number of digits is even (4+2=6),so number of bytes
used will be 6/2 +1 =4 bytes.
in this example first half byte will be having 0000 value
this will be ignored while reading from data. the next six
half bytes will be having the six digits of data. and then
the last half byte will be having the sign value as said in
the example 1.
example 3
s9(4) comp3
4-even
first half byte no data(0000). next 4 half bytes data. the
last half byte will have sign value
Thanks
