Explanation
1. This instruction adds the 32-bit single-precision floating-point numbers in S
2. Instruction flags: SM600 (zero flag), SM601 (borrow flag), and SM602 (carry flag)

When the operation result is zero, SM600 is ON. Otherwise, it is OFF.

When the absolute value of the operation result is less than the value that can be represented by the minimum
floating-point number, the value in D is 16#FF800000 and SM601 is ON.

When the absolute value of the operation result is larger than the value that can be represented by the
maximum floating-point number, the value in D is 16#7F800000 and SM602 is ON.
Example
Adding single-precision floating-point numbers: when X0.0 is ON, the instruction adds the addend 16#4046B852 in (D21,
D20) to the augend 16#3FB9999A in (D11, D10), and stores the sum 16#4091C28F in (D31, D30). 16#4046B852,
16#3FB9999A, and 16#4091C28F represent the floating point numbers 3.105, 1.450, and 4.555 respectively.
