What "The number of Voronoi layers to sum" means?

During the process translating the Blender’s UI, I encountered this phrase. Unfortunately I do not have a mean to download latest Blender’s releases to test out and see for myself, I am working on a 5,1 Mac Pro, which only allowed me to install Blender 3.4.1 the latest, further versions will not allow me to install. If you know what it means. It is mentioned in this source file:

The explanation for this ‘Detail’ option in the documentation is:

Detail

Number of noise octaves. The fractional part of the input is multiplied by the magnitude of the highest octave. Higher number of octaves corresponds to a higher evaluation time.

Thank you in advance

it’s very similar to Detail value in the noise texture node but applied to voronoi,

The addition in 4.0 allows to mix several layers of voronoi, each with different size, which lead to more detailed and interesting pattern.

Detail is not exactly how many layers are stacked, since it’s a float value instead of a integer, but anyway, increasing the value stacks more layer.

As said it’s very similar to noise node.

Thank you ever so much!
