S+1, S+2….. S+n: set values of multi-point areas. S+1 must be the minimum value, S+2 must
be larger than S+1 and so on. Therefore, S+n must be the maximum value.
D: output value gotten from the proportional value calculation
D+1, D +2 … D+n: the range of values gotten from the proportional value calculation
n: set values of multi-point areas. The range of set values is K2~K50. When the set value
exceeds the range, it will not be executed.
The sample curve: (n is set to be K4)

The explanation of the sample:
1. When input value S is larger than S+1 (S
1
for short) and smaller than S+2 (S
2
for short), D+1
(D
1
for short) and D+2 (D
2
for short), D= ( ( S – S
1
) x ( D
2
– D
1
) / ( S
2
– S
1
) ) + D
1.
2. When input value S is smaller than S+1, D= D+1; when input value S is larger than S+n, D=
D+n.
3. The operation of instructions uses floating-point values. After the decimal value of the
output values is omitted, the value will be output in the 16-bit form.
K13: Proportional Value Calculation Function of Multi-point Areas (32-bit values)
The explanations of source and destination devices are illustrated as the explanation of K12,
but devices S and D are indicated by 32-bit values.
K14: Proportional Value Calculation Function of Multi-point Areas (floating-point values)
The explanations of source and destination devices are illustrated as the explanation of K12,
but devices S and D are indicated by 32-bit floating-point values.
K15: to Calculate the local time for sunrise and sunset
Explanation on operands S, D, m, n:
S:
S +0, S+1: the local longitude (floating-point format)
S+2, S+3: the local latitude (floating-point format)
