Linear interpolation between range values

Hi All,

 

How to compute the Linear interpolation between range of values?

 

Source Table:

IDVAL
1233.13
1244.22
1252.35

 

Lookup Table:

low_valhigh_valpct
22.25110.25
2.53112.2
3.253.5115.25
3.754120
4.254.75125

 

 

 

ID-123 is interpolated between 

2.53112.2
3.253.5115.25

 

Interpolated value= (3.13 - (2.5+3)/2)/((3.25+3.5)/2-(2.5+3)/2) * (115.25-112.2) + 112.2=114.0544

 

 

Target:

IDVALInterpolated_pct
1233.13114.0544
1244.22122.76
1252.35110.952

 

 

Thanks,

Mark

Hi @mark_paul ,

 

you can use Append Fields, Filter and Sample to solve the problem:

I've attached a sample workflow. Let me know if it works for you.

 

Best,
