@ -5,9 +5,12 @@ This RFC proposes introducing a second parameter to `math.round` to allow users
```luau ```luau
print( math.round(3.1415, 2) ) -- Output: 3.14 print( math.round(3.1415, 2) ) -- Output: 3.14
``` ```
In doing so, we:
- Improve user convenience by providing an implementation of the behavior for them
- Provide a marginally more performant alternative to existing implementations
## Motivation ## Motivation
The motivation for this proposal lies solely in improving user convenience. Albeit very simple, the concept's current implementation (demonstrated in **Design**) has two major flaws: The motivation for this proposal lies mostly in improving user convenience.
