pub const fn to_degrees(self) -> Self;
pub const fn to_radians(self) -> Self;
pub const fn max(self, other: Self) -> Self;
pub const fn min(self, other: Self) -> Self;
pub const fn clamp(self, min: Self, max: Self) -> Self;
pub const fn abs(self) -> Self;
pub const fn signum(self) -> Self;
pub const fn copysign(self, sign: Self) -> Self;
}
```
