# Not a Number of Floating Point Problems

By: Gary T. Leavens

# Abstract

Floating-point numbers and floating-point arithmetic contain some surprising pitfalls. In particular, the widely-adopted IEEE 754 standard contains a number that is “not a number,” and thus has some surprising properties. One has to be extremely careful in writing assertions about floating point numbers, to avoid these pitfalls.
