Processing details
• These instructions divide the single-precision real number in the device specified by (s1) by the single-precision real
number in the device specified by (s2), and store the result in the device specified by (d).
(s1)+1 (s1)
Single-precision real number
• When the constant (K or H) is specified in (s1) and (s2), these instructions convert values into single-precision real number
automatically.
