As discussed in the previous chapter, working with big integers is an abstract art, and if the schemes are not implemented properly, the entire cryptographic algorithm or scheme can lead to a real disaster.

This chapter is dedicated to floating-point arithmetic and its importance for cryptography.

Why Floating-Point Arithmetic?

Floating-point arithmetic represents a special type of arithmetic which requires caution due to the representations and methods of implementations. ...
