6.6 Converting Floating-Point Expressions to Assembly Language
Because the FPU register organization is different than the 80x86 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 calculator, ...
