Scientific Numbers in Logstash - How to handle them? Need help

[Datakids (Thorben)]

Hi there,
I have found below mentions post which is a bit helpfull but I dont know how to split a Scientific Notation and merge them afterwards
.
A few examples of the numbers I want to handle or to learn how to handle in logstash:

2,3500000000000000E+02
-3,3000000000000000E+01
2500000000000000E+03

I tried also with grok but not yet found the right way:

(?<name-of-field>[([0-9] [+\-]? [0-9])]+)

Grok pattern to format a special date and scientific notation number

Hi, I'm looking for two special patterns to convert a date with a special format and to convert a number with scientific notation. For the date, I've got this format yyyyMMdd_hh:mm:ss (ex: 20181204_10:50:07) For the scientific notation, here's what I've got and what I want : 2.474731e+01 => 24.74731 2.211762e+00 => 2.211762 9.629999e-01 => 0.9629999 Thanks for your help

Hope you can help me
Thanks and regards
