Generate a list of number with interval in Groovy

I'm learning Groovy. I want an array of numbers from 0 to n with interval 0.1.

double arr=[0,0.1,0.2....n]

I could write a java style for-loop, but is there a easier syntax to do this? I know Groovy has a lot of syntactic sugar.

there was an exact question here earlier

n=10;(0..10*n).collect{it/10}

there are no decimal step values for Groovy's ranges currently

I would go with 0.0..10.0.collect{it/10.0} but maybe there is clever way to do it by specifying increments.
