Ref

A small Jai library for making it easy to share pointers/references to the same data, while making it easy to get rid of the pointer/reference when it is no longer needed.

How to use

Creating a Ref variable

You just create a variable using with the Ref(T) type, where you replace T with your type. For example Ref(int).

Initializing

Then you initialize it with init(*ref_variable) where ref_variable is your variable,

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
