6.7. 6.7 Converting Floating Point Expressions to Assembly Language
Because the FPU register organization is different than the 80×86 integer register set, translating arithmetic expressions involving floating point operands is a little different than the techniques for translating integer expressions. Therefore, it makes sense to spend some time discussing how to manually translate floating point expressions into assembly language.
In one respect, it's actually easier to translate floating point expressions into assembly language. The stack architecture of the Intel FPU eases the translation of arithmetic expressions into assembly language. If you've ever used a Hewlett-Packard calculator, you'll be right at home on the FPU because, like the HP ...
