It seems to me that you are trying to read a “String representing a floating-point-number (fpn)” as an “int” in one step. That is never going to work well, you need to convert the string to a float then convert the float to an int by rounding like this String receivedString = "-0.2132143214321, 109…

Please format the start of your code correctly… I believe the Java trim method does not belong specifically to processing so maybe try your question on Stack Overflow

If it is a “string float” then parse it to a “number float” and then you can cast it to a “number int” (you will lose decimal points). String a = " 1.2345 \n"; //Added spaces and a \n so there was something to trim. println(float(a.trim())); println(float(trim(a))); println(int(float(a.trim())))…

I tried the code that you wrote thanks for trying but it didn’t help I have to send multiple values from arduino to Processing and that code doesn’t work when I try that. If you can edit the code I owe you By the way data’s are like: -0.2132143214321,109.123214,-30.3214321

[image] SouSageYa: If you can edit the code I owe you This is your project; I will only provide guidance. I modified your String to have a line feed at the end; I assume you are using println() on the Arduino side and it will send this and trim() will remove that. You are trying to parse a …

Thank you for the solution of the trimming but it turns out there is something else with this code as you can see I created values as Val1 for example and I defined them as “Integer.parseInt(a[6].trim());” I have to have the numbers like that so I can push them on chart

My code produces an array of ints which can be added to a chart. v[] is an array of integers

Thank you for all you are the best. Much love from Turkey
