Struct Decimal256

pub struct Decimal256 {
    pub scale: u8,
    pub value: i256,
}

Represents a decimal number with 256-bit precision.

This structure provides the highest level of precision for decimal numbers, capable of representing extremely large values with exact decimal precision. Useful for cryptographic applications, high-precision scientific calculations, or any domain requiring arithmetic beyond 128-bit precision.

Fields

scale: u8

Number of decimal places

value: i256

The actual value, scaled by 10^scale

Implementations

impl Decimal256

pub fn to_float64(&self) -> f64

Converts the decimal value to a floating-point representation.

For extremely large values, significant precision loss may occur as f64 has much lower precision than i256.

Trait Implementations

impl Clone for Decimal256

fn clone(&self) -> Decimal256

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Decimal256

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

Formats the value using the given formatter.
