Function
The data specified in S1 and the data specified in S2 are added (+D(845)), subtracted (-D(846)),
multiplied (∗D(847)), or divided (/D(848)) as double-precision floating-point data (64 bits: IEEE754) and
the result is output to D+3, D+2, D+1, and D.

Error Flag P_ER • ON when S1 or S2 is not treated as floating-point data.
•+D
•ON if the augend or addend data is not a number (NaN).
•ON if +o is added to -o.
•-D
•ON if the minuend or subtrahend is not a number (NaN).
•ON if +o is subtracted from +o.
•ON if -o is subtracted from -o.
• ∗D
•ON if the multiplicand or multiplier is not a number (NaN).
•ON if +o and 0 are multiplied.
•ON if -o and 0 are multiplied.
•/D
•ON if the dividend or divisor is not a number (NaN).
•ON if the dividend and divisor are both 0.
•ON if the dividend and divisor are both +o or -o.
• OFF in all other cases.
Equals Flag P_EQ • ON if both the exponent and mantissa of the result are 0.
• OFF in all other cases.
Overflow Flag P_OF • ON if the absolute value of the result is too large to be expressed as a double-precision floating-point
value.
Underflow Flag P_UF • ON if the absolute value of the result is too small to be expressed as a double-precision floating-point
value.
Negative Flag P_N • ON if the result is negative.
• OFF in all other cases.
