Explore floating-point differences between x86 and Arm

About this Learning Path

Who is this for?

This is an introductory topic for developers who are porting applications from x86 to Arm and want to understand how floating-point behavior differs between these architectures - particularly in the context of numerical consistency, performance, and debugging subtle bugs.

What will you learn?

Upon completion of this learning path, you will be able to:

• Identify key differences in floating-point behavior between the x86 and Arm architectures.
• Recognize the impact of compiler optimizations and instruction sets on floating-point results.
• Apply compiler flags and best practices to ensure consistent floating-point behavior across platforms.

Prerequisites

Before starting, you will need the following:

• Access to an x86 and an Arm Linux machine.
• Familiarity with floating-point numbers.
