They DO use a lookup table because that’s what the FDIV but came from:

https://en.m.wikipedia.org/wiki/Pentium_FDIV_bug

“It is implemented using a programmable logic array with 2,048 cells, of which 1,066 cells should have been populated with one of five values: −2, −1, 0, +1, +2.”

Not sure what you’re trying to demonstrate, they wouldn’t store every single float!! I hope don’t program. ;)
