4. 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
5. The equation to obtain the operation equation of the instruction:
y = kx + b
where
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
6. Substitute the above parameters into y = kx + b and the operation instruction can be obtained. y
= kx + b = D = k S
1
+ b = slope × S
1
+ offset = slope × S
1
+ min. destination value – min. source
value × slope = slope × (S
