6.9 Putting It All Together

This chapter finished the presentation of the integer arithmetic instructions on the 80x86. Then it demonstrated how to convert expressions from a high level language syntax into assembly language. This chapter concluded by teaching you a few assembly language tricks you will commonly find in programs. By the conclusion of this chapter you are (hopefully) in a position where you can easily evaluate arithmetic expressions in your assembly language programs.

Between the FPU and the HLA Standard Library, floating point arithmetic is actually quite simple. In this chapter you learned about the floating point instruction set and you learned how to convert arithmetic expressions involving real arithmetic into a sequence of floating point instructions. This chapter also presented several transcendental functions that the HLA Standard Library provides. Armed with the information from this chapter, you should be able to deal with floating point expressions just as easily as integer expressions.
