"""zfp is an open source C library for compressed floating-point arrays
that supports very high throughput read and write random acces,
target error bounds or bit rates. Although bit-for-bit lossless
compression is not always possible, zfp is usually accurate to
within machine epsilon in near-lossless mode, and is often orders
of magnitude more accurate than other lossy compressors.
