Struct Decimal128

pub struct Decimal128 {
    pub scale: u8,
    pub value: i128,
}

Represents a decimal number with 128-bit precision.

Similar to Decimal64 but with a larger range, this structure can represent very large decimal numbers with high precision, suitable for financial calculations and other domains requiring exact decimal arithmetic beyond 64-bit limits.

Fields

scale: u8

Number of decimal places

value: i128

The actual value, scaled by 10^scale

Implementations

impl Decimal128

pub fn to_float64(&self) -> f64

Converts the decimal value to a floating-point representation.

Note that for very large values, this conversion may lose precision as f64 has limited precision compared to i128.

Trait Implementations

impl Clone for Decimal128

fn clone(&self) -> Decimal128

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Decimal128

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
