Explanations:
1. See the specifications of each model for the range of operands.
2. Flags: M1162 (decimal integer or binary floating point); M1162 = On -> Binary floating point

5. Operation equation in the instruction: D = [(S
1
– min. source value) × (max. destination value – min. destination
value)] ÷ (max. source value – min. source value) + min. destination value
6. The operational relation between source value and destination value is as stated below:
y = kx + b
y= Destination value (D)
k= Slope = (max. destination value – min. destination value) ÷ (max. source value – min. source value)
x= Source value (S
1
)
b= Offset = Min. destination value – Min. source value × slope
Bring all the parameters into equation y = kx + b and obtain the equation in the instruction:
y = kx + b = D = k S
1
+ b = slope ×S
1
+ offset = slope ×S
1
+ min. destination value – min. source value × slope
