Doing a table lookup for common cases and computing for the less common ones is perfectly valid!

And for some problems it's even efficient. Not factorial, though.

Oh you're right, hive mind, it's efficient. Sorry.

Not 100% sure but I believe this is how we landed the lunar module on the moon the first time...tan/arctan/both were too hard to compute on the processors of those days so they discretized into half angles & stored the tangents in a lookup table.

That's how early calculators worked, and some fast math libraries today too.

The Pentium FDIV bug was due to a bad value in a lookup table.
