Mojo trait
Roundable
The Roundable
trait describes a type that defines a rounding operation.
Types that conform to Roundable
will work with the builtin round
function. The round operation always returns the same type as the input.
For example:
@value
struct Complex(Roundable):
var re: Float64
var im: Float64
fn __round__(self) -> Self:
return Self(round(re), round(im))
@value
struct Complex(Roundable):
var re: Float64
var im: Float64
fn __round__(self) -> Self:
return Self(round(re), round(im))
