math.lerp is displayed in intellisense, but the function does not exist.
Expected behavior
math.lerp should exist…

The function hasn’t been enabled yet, not sure why it was added to the intellisense a bit early though.

Understood, then it’s poor user experience. Time to try CLI for the first time
Thank you for the report.
Closing as a duplicate.
Apologies for the outward frustration. I did test math.lerp in Luau via Homebrew and it’s nice to see the performance increase when calling math.lerp vs doing the arithmetic in Luau.
I would love to be able to do this via vector types too due to my current project working on a raytracing renderer, but there are other ways I can look into gaining performance.
Both vector2 and vector3 have a Lerp function which can be used directly on the data type. Is there a particular inefficiency / inaccuracy with these methods that math.lerp doesn’t have, or am I misunderstanding the use-case? I’m just genuinely curious about if there is something wrong with these functions as I’ve used them many-a-time.

Trying to keep my code as pure Luau as possible for portability reasons.
HOWEVER.
I don’t know why I didn’t think of this, since I have already extracted some roblox datatype methods into localised functions for speed increases in perf. critical code, but I am able to pass Luau vector types into the Vector3 Lerp function, and it works! Thank you for saving me time on this.
My initial confusion is that the --!strict linter gets funny since vector and Vector3 is not really the same type, so I would probably just have to shut that up if I can.
EDIT: Just tried using Vector3.Lerp vs Luau math. It is still slower than performing arithmetic. Bleh.
