My experience is that this loss of precision is hardly ever a practical problem in the real world of scientific development; in practice floating-point numbers are almost universally IEEE 754 doubles (perhaps sometimes single-precision in large datasets, like seismic SEG-Y files; occasionally IBM format hex floats; but IEEE 754 doubles are by. The introduced system is written in Python and utilizes a big data framework called “DASK” for parallel and distributed processing of traces over a number of computers to gain better performance. Opens a segy file and tries to figure out its sorting, inline numbers, crossline numbers, and offsets, and enables reading and writing to this file in a simple manner.
