Processing details
• These instructions subtract the single-precision real number in the device specified by (s2) from the single-precision real
number in the device specified by (s1), and store the result in the device specified by (d).
• When the constant (K or H) is specified in (s1) and (s2), these instructions convert values into single-precision real number
automatically.
