Floating Point Precision in x86-64 Assembly

Floating Point Precision in x86-64 Assembly

The lack of precison you get with floating point numbers isn't a language problem, it's a problem with floating point nubers themselves, so it even shows up as low as x86-64 assembly.

The assembly in the file bellow is the code I have written to showcase this.

To compile it you have to do this:

$ nasm floats.asm -o floats.o -f elf64

Bash scripting best practices (copied from https://github.com/progrium/bashstyle/blob/master/README.md)

progrium/bashstyle

Bash is the JavaScript of systems programming. Although in some cases it's better to use a systems language like C or Go, Bash is an ideal systems language for smaller POSIX-oriented or command line tasks. Here's three quick reasons why:

  • It's everywhere. Like JavaScript for the web, Bash is already there ready for systems programming.
  • It's neutral. Unlike Ruby, Python, JavaScript, or PHP, Bash offends equally across all communities. ;)
  • It's made to be glue. Write complex parts in C or Go (or whatever!), and glue them together with Bash.

This document is how I write Bash and how I'd like collaborators to write Bash with me in my open source projects. It's based on a lot of experience and time collecting best practices. Most of them come from these two articles, but here integrated, slightly modified, and focusing on the most bang for buck items. Plus some ne
