Whenever we see fractionals we automatically pick the floating-point (FP) data types, such as float or double. However, is it always optimal? What other choices we have? Are there any other standards than the IEEE 754 FP? In this talk I’ll present such topics as:

  • Brief intro to the FP IEEE 754 standard, its pros, cons and pitfalls.
  • How can we compress floating point data – shorter formats, lossless & lossy compressions, new ZFP and SZ methods and their use in C++.
  • A new kid on the block – the POSIT arithmetic and how to use it.
  • Intro to the relevant C++ libraries and – as always – a lot of practical examples. Everybody is invited ;)
