pub trait DecimalTrait

Trait functions

from_int

Create a decimal from an integer part

Fully qualified path: alexandria_math::decimal::DecimalTrait::from_int

fn from_int(int_part: u64) -> Decimal

from_parts

Create a decimal from integer and decimal parts (user-friendly) int_part: integer portion (e.g., 3 for 3.35) decimal_part: decimal portion as integer (e.g., 35 for 0.35) Example: from_parts(3, 35) creates 3.35, from_parts(56, 678) creates 56.678

Fully qualified path: alexandria_math::decimal::DecimalTrait::from_parts

fn from_parts(int_part: u64, decimal_part: u64) -> Decimal

from_raw_parts

Create a decimal from integer and raw fractional parts (internal use) frac_part should be in range [0, 10^18) - raw DECIMAL_SCALE units

Fully qualified path: alexandria_math::decimal::DecimalTrait::from_raw_parts

fn from_raw_parts(int_part: u64, frac_part: u64) -> Decimal

from_raw_parts_signed

Create a signed decimal from integer and raw fractional parts (internal use) frac_part should be in range [0, 10^18) - raw DECIMAL_SCALE units

Fully qualified path: alexandria_math::decimal::DecimalTrait::from_raw_parts_signed

fn from_raw_parts_signed(int_part: u64, frac_part: u64, is_negative: bool) -> Decimal

from_felt

Create a decimal from a felt252 (treating it as integer) Note: This method treats all felt252 values as positive For negative values, use from_felt_signed or other constructors

Fully qualified path: alexandria_math::decimal::DecimalTrait::from_felt

fn from_felt(value: felt252) -> Decimal

from_felt_signed

Create a signed decimal from a felt252

Fully qualified path: alexandria_math::decimal::DecimalTrait::from_felt_signed

fn from_felt_signed(value: felt252, is_negative: bool) -> Decimal

from_parts_signed

Create a signed decimal from integer and decimal parts (user-friendly) int_part: integer portion (e.g., 3 for 3.35) decimal_part: decimal portion as integer (e.g., 35 for 0.35) is_negative: sign of the number Example: from_parts_signed(3, 35, true) creates -3.35

Fully qualified path: alexandria_math::decimal::DecimalTrait::from_parts_signed
