Efficient rounding

[SanjoSolutions]

I have seen some places where a rounded number is required instead of a string.
Here is an efficient implementation of round in Lua: https://github.com/SanjoSolutions/LuaMathematics/blob/fe7048955fb41c03c4cbd6f1dfb94d3b65115d7d/Mathematics.lua#L27-L33
You can copy it.

hm there is a gutil round already, in what way is it not efficient?

[SanjoSolutions]

It converts the number to a string. And when the caller requires a number, the caller seems to convert the string back to a number. That seems computational less efficient than the linked implementation.
