Struct Decimal128

pub struct Decimal128 { /* private fields */ }

Microsoft’s decimal128

Please note that this is NOT BSON compliant data.

This struct is only for storing / passing data, so most mathematical operations are not implemented (yet)

Implementations

impl Decimal128

pub const ZERO: Decimal128

pub const MAX: Decimal128

pub const MIN: Decimal128

pub const fn from_bytes(bytes: [u8; 16]) -> Option<Decimal128>

Construct a new decimal128 from raw representation

Returns None if the representation is not valid

pub const fn new(mantissa: u128, exponent: u32, is_negative: bool) -> Decimal128

Construct a new decimal128 from raw parts

The result value would be mantissa * 10 ^ -exponent * (if is_negative { -1 } else { 1 }) where ^ is power

Panics

This function panics if:

• mantissa is greater than 1 << 96
• exponent is greater than 28

pub const fn new_signed(mantissa: i128, exponent: u32) -> Decimal128

Construct a new decimal128 from raw parts with mantissa and exponent

The result value would be mantissa * 10 ^ -exponent * (if is_negative { -1 } else { 1 }) where ^ is power

Panics

This function panics if:

• mantissa is greater than 1 << 96
• exponent is greater than 28

pub const fn parse(s: &str) -> Option<Decimal128>

Parses the string and converts to Decimal128.

Decimal is only supported.

pub fn bytes(&self) -> [u8; 16]

pub const fn abs(self) -> Self

pub fn round_digits(self, digits: u32) -> Self

pub fn to_f64(&self) -> f64

pub fn to_i64(&self) -> Option<i64>
