Hey!

Can you write the (float) value of an address to a Label as an integer?
My Code is like that:

Code:
  local memrec=addresslist_getMemoryRecordByDescription(getAddressList(), "Time")
  local value=memoryrecord_getValue(memrec)
  control_setCaption(UDF1_CELabel2, value)

Code:
UDF1.CELabel2.Caption = getAddressList().getMemoryRecordByDescription("Time").Value:match("^%d+") or "0"

Thank you for your answer.
Code:
.Value:match("^%d+")

So this converts a float into an integer?

And could you also do something like this?:
Code:
UDF1.CELabel2.Caption = getAddressList().getMemoryRecordByDescription("Time").Value:match("^%d+") or getAddressList().getMemoryRecordByDescription("TimeNrTwo").Value:match("^%d+")

No. The string.match function is used for taking one string (the value field) and finding a particular part of it that matches a specified pattern ("^%d+"). The or operator makes it such that if string.match didn't find anything that matches the pattern, it will just return 0. If that's the behavior you want, then go with what you wrote. If not, explain what you want.

Also, I forgot to include negative numbers with that pattern.
Code:
UDF1.CELabel2.Caption = getAddressList().getMemoryRecordByDescription("Time").Value:match("^-?%d+") or "0"
If you want to include NaN or +-Inf, make separate checks for that.
