Operands:

S1: Source value S2: Parameters D: Operation result

Explanations:

1.SCLP instruction performs a proportional calculation according to the internal slope equation as well as the parameters set in this instruction.

2.Settings of S2 for 16-bit instruction (occupies 4 consecutive devices):

Device No.	Parameter	Range
S2	Max. source value	-32768~32767
S2+1	Min. source value	-32768~32767
S2+2	Max. destination value	-32768~32767
S2+3	Min. destination value	-32768~32767

3.Settings of S2 for 32-bit instruction (occupies 8 consecutive devices).

Device No.	Parameter	Range
		Integer
S2、S2+1	Max. source value
S2+2、3	Min. source value	-2,147,483,648~2,147,483,647
S2+4、5
	Max. destination value
S2+6、7	Min. destination value

Floating point number

Range of 32-bit floating point number

4.Operation equation in the instruction: D = [(S1 – 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 (S1)

b = Offset = Min. destination value – Min. source value × slope
