pub fn checked_add(self, other: Self) -> Result<Self>

Checked addition.

pub fn checked_sub(self, other: Self) -> Result<Self>

Checked subtraction.

pub fn checked_scale(self, millionths: i64) -> Result<Self>

Checked multiplication by a fixed-point millionth ratio.

pub fn as_points_f64(self) -> f64

Returns a floating-point value for output APIs only.
