For ipairs for table differences

[savaskorkmaz]

Hi ,

I have 3 tables like. Those are the Group names.

temp = { 'Temp 1', 'Temp 2', 'Temp 3' }
diff = { 'Diff 1', 'Diff 2', 'Diff 3' }
result = { 'Result 1', 'Result 2', 'Result 3' }


I need to calculate
Temp 1 - Diff 1 and write to Result 1

How can i do via for ipairs loop 

Regards,

Hi Try like this 

Code:

temp = { '20', '22', '5' }
diff = { '17', '18', '19' }

result ={}

for i = 1, #temp do
 
  result[i] =  temp[i] - diff[i]
 
end

log(result)

Use this code if each table member is a group address or an object name. Make sure that each table has the same number of elements.

Code:

temp = { 'Temp 1', 'Temp 2', 'Temp 3' }
diff = { 'Diff 1', 'Diff 2', 'Diff 3' }
result = { 'Result 1', 'Result 2', 'Result 3' }

for i, res in ipairs(result) do
  val = grp.getvalue(temp[ i ]) - grp.getvalue(diff[ i ])
  grp.write(res, val)
end
