as follows.
The value in D is 1 because the floating-point number in S
1
is a negative number.
The value stored in (D+2, D+1) is 16#3225550. (The floating-point number is converted into
the seven-digit binary-coded decimal number, and the seven-digit binary-coded decimal
number is rounded off).
The value in D+3 is 1 because the exponent is a negative number.
The value in D+4 is 4.
If the floating-point number in S
1
is -1.32165E+2 and the value in S
2
is 3, the conversion result
is as follows.

-1.32165E+2 is equal to 132.165. Since the value in S
2
is 3, the decimal point in the
floating-point number in S
1
is moved to the right by three decimal places. The floating-point
number in S
1
becomes -132165.
-132165 is equal to -1321650E-1. The binary-coded decimal floating-point number format is as
follows.
The value in D is 1 because the floating-point number in S
1
is a negative number.
The value stored in (D+2, D+1) is 16#1321650. (The floating-point number is converted into
the seven-digit binary-coded decimal number, and the seven-digit binary-coded decimal
number is rounded off).
The value in D+3 is 1 because the exponent is a negative number.
The value in D+4 is 4.

Since the value in D4 is 3, the decimal point in 1.963852741 in (D1, D0) is moved to the right by
three decimal places. The floating-point number in (D1, D0) becomes 1963.852741.
The value in D10 is 0 because the floating-point number in S
1
is a positive number.
1963.852741 is equal to 1963852E-3. The binary-coded decimal floating-point number format is as
follows.
The value stored in (D12, D11) is 16#1963850. (The floating-point number is converted into the
seven-digit binary-coded decimal number, and the seven-digit binary-coded decimal number is
rounded off).
The value in D13 is 1 because the exponent is a negative number.
The value in D14 is 3.
