The following methods can be defined to implement container objects.
Containers usually are [ sequences ](../glossary.html#term-sequence) (such as

value ` x ` is _truthy_ or _falsy_ , Python applies ` bool(x... | |

Are there any lossless compression methods that can be applied to floating
point time-series data, and will significantly outperform, say, writing the
data as binary into a file and running it through gzip? | |

Post answer | |
wiki_function/lossy-compression-algorithms7_92_0.txt | Applying a 2D Haar Transform for the second level, yields a linear decrease of
the image size:
The calculated differences and image decrease allow for the image to be
compressed with less data while keeping an eye on quality.
More compression means lower quality and higher quality means lower
compression. | |
