8 APPLICATION INSTRUCTION
8.9 Real Number Instruction
Multiplying single-precision real numbers
DEMUL(P)
These instructions multiply the single-precision real number in the device specified by (s2) to the single-precision real number
in the device specified by (s1), and store the result in the device specified by (d).

Processing details
• These instructions multiply the single-precision real number in the device specified by (s2) to 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.
