I have numbers like
1.553
23
2.383
26
566
When I parse this with logstash, I get string value of these.
When I try to use mutate filter plugin like below;
mutate {
convert => {
"number_field" => "integer"
}
}
It returns wrong.
I mean as an example,2.383 as input goes 2 as output.
My expections is below
1553
23
2383
566
How can i solve this ?
Thanks for answering
When mutate+convert is used to convert to integer it will truncate floats. You can use integer_eu to tell it that the a dot is used instead of a comma to separate thousands (e.g., "1.000" produces an integer with value of one thousand).

I`m new to Postscript, and I was wondering how to get the nth character of a string in postscript.
If I do something like
(hello) 1 get
then 101 is pushed on the stack (ASCII 101 corresponds to "e")
how to convert that 101 to the corresponding "e" character as string (e)?
or how to compare it to a string (e) such that i can tell it is in fact some char 'e'?
so how to say something like
101 === (e) ?
I am somewhat confused by your output as ASCII 'e' should be 101 according to every source I have at hand including running your code using gs. That said you probably want to use getinterval instead of get as it returns a string.
(hello) 1 1 getinterval
I have an element in a CSV file that has a value of 0.022222222. Naturally, this hits the float data type limitation. However, logstash is converting it to the scientific notation.
I want the value in Elasticsearch to be float and not string. How can I achieve that?
Logstash and ES 7.1.0
Thanks in advance
try the below code
mutate {
convert => {
"fieldname" => "float"
}
}
I have an array which outputs the following:
charges = [5.00, 26.00, 8.00, 4.00, 4.00, -8.00, 54.00, 52.48]
When I try to perform a sum using this:
charges.sum()
It gives me:
5.0026.008.004.004.00-8.0054.0052.48
I am assuming I need to convert it from a string to a float so I did:
Float.valueOf((String) charges.sum())
and it gives me an error which states 'multiple points'.
My question is how do I add all of these figures up?
If your list is actually of strings, you can quickly do the conversion with sum()'s closure form.
charges.sum { it.toBigDecimal() }
It is unclear what your list has in it, it seems like the entries in your list are actually strings (since sum concatenates them), or something that prints a string value (has a toString method that returns a string showing the value so you think it is numeric even though it isn’t) . They are definitely not numeric, so convert each of them to a numeric type before summing:
charges.collect { new BigDecimal(it.toString()) }.sum()
(What your code was doing was concatenating the string values together, then converting that to a numeric type.)
You must delete the cast (String)
Float.valueOf(charges.sum())
I'd like to take a String e.g. "1234" and convert it to an Integer which represents the sum of all the characters.
I thought perhaps treating the String as a List of characters and doing a reduce / inject, would be the simplest mechanism. However, In all my attempts I have not managed to succeed in getting the syntax correct.
I attempted something along these lines without success.
int sum = myString.inject (0, { Integer accu, Character value ->
return accu + Character.getNumericValue(value)
})
Can you help me determine a simple syntax to resolve this problem (I can easily solve it in an java like verbose way with loops etc)
Try:
"1234".collect { it.toInteger() }.sum()
Solution by #dmahapatro
"1234".toList()*.toInteger().sum()
I've been trying different ways to read this hex string, and I cannot figure out how. Each method only converts part of it. The online converters don't do it, and this is the method I tried:
function string.fromhex(str)
return (str:gsub('..', function (cc)
return string.char(tonumber(cc, 16))
end))
end

This simply gives me a bunch of gibberish surrounded by a few readable strings.
Could someone please tell me how to convert the entirety of this string into readable format? Thank you!
Break your packedStr in parts of 2
1b = 27
4c = 76
75 = 117
61 = 97
and so forth. When you use string.char() with the resulting decimal output, it converts them to equivalent ASCII values. Of the total possible 256 ASCII values in extended ASCII table, only 95 are printable characters.
Thus, you'll always receive the gibberish text. Here's what you'd receive when trying to print each of the character separately: http://codepad.org/orM7pmAb and that is the only possible "readable" output.
