Chapter 6 Applied Instructions Example Subtracting 32-bit single-precision floating-point numbers: when M0 is ON, the instruction subtracts the subtrahend in (D21, D20) from the minuend in (D21, D20), and stores the difference in (D31, D30). Additional remarks If the value in S 1 or the value in S 2 exceeds the range of values that can be represented by the floating-point numbers, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2013. 6_ 6-59
