How to calculate random no

[Shekhar_Pandey]

hello..

Anybody know how to generate random numbers between 0 to .5 using logstash.
I use the following code but not working..

ruby {
code => 'event.set("randomNumber", rand(100).to_i())'
}

Thanks

Here is solution so anybody can use this...

filter{
ruby {
code => 'event.set("randomNumber", ((rand() *0.9).to_f))'

}

}
