083. AQA A Level SLR11 Floating point normalisation – Recap
About this video
AQA Specification Reference
A Level 4.5.7.8
This video continues our journey into binary floating point representation by working through some additional examples of normalisation.
Key questions:
- How does a computer store fractions (real numbers)?
- What do we mean by a normalised floating-point binary number?
- How do you normalise both positive and negative floating-point binary numbers?
