How do the math functions from the math.h library work? How can you add, subtract, divide, multiply, raise to a power, find a root, etc. without using binary operators? What is the logic behind your day-to-day mathematic operations? and how can you teach it to a computer?

Continuing from where we left off from lmr0, after making bitwise operator functions:

• Not
• And
• Nand
• Or
• Nor
• Xor
• Xnor
• Logical shift
• Logical rotate

This week we will be focusing on creating functions that do basic algorithm operations.

*Our task is to ask questions on Discord or in class and document our findings on this wiki page collaboratively, regarding the functionality of this project.

*For anybody interested in editing the wiki page, here is the dokuwiki user guide: https://www.dokuwiki.org/wiki:syntax#basic_text_formatting -Ash

Determine a unified means of output so that all submissions have an identical format.

Two main ways to approach this project: the more laid out approach, and the straight to the point approach. You can either do the bitwise portion of each mathematical operator and convert it to the bit array, or, just work with the bit array from the start. If you work with the bit array from the start, you might find some functions easier, but some functions could also be harder. There really isn't a “recommended” approach just whatever way you find easier to interpret and understand.

Derive a set of tests that all submissions should perform to ascertain correctness (state the tests, the inputs, and the expected outputs). In conjunction with conforming output specifications, all submissions should match (this is the basis for writing a verification script that can automate the process).

Which, being said: once output specifications and verification tests have been established, anyone writing a verification script to automate this can be eligible to receive bonus points.
