Summary of the discussion in 2004 (without IEEE 754-2008 knowledge of course):
- An agreed floating point number format
- 6502 conversion routines from int <-> float and back
- 6502 routines to support + - * / < > <= >= == != operators
- changes of the compiler, assembler and linker
- 6502 ASCII <-> FP conversion functions (e.g. for scanf/printf)
- A 6502 math library (pow(), exp(), sin(), cos(), ... the works)
32 bit | 48 bit |

IEEE 754-2008 (archived)
Steve Wozniak's implementation
cc65-floatlib is "a naive approach for using kernal floating point numbers on C64, while using IEEE float values at application level"
