Crate ancdec 

A #![no_std] fixed-point decimal library with four types for different precision/size needs.

Type	Integer/Frac	Scale	Size
AncDec8	u8	0-2	4 bytes
AncDec32	u32	0-9	12 bytes
AncDec	u64	0-19	24 bytes
AncDec128	u128	0-38	40 bytes

All types store integer and fractional parts separately with an explicit scale, avoiding the precision loss inherent in floating-point representations.

Feature flags

• dec8 / dec32 / dec64 / dec128 – enable individual types (all on by default)
• serde – string-based Serialize/Deserialize
• sqlx – PostgreSQL NUMERIC support (implies std + dec64)

Structs

AncDec

64-bit fixed-point decimal (u64 int/frac, 19-digit precision, 24 bytes).

AncDec8

8-bit fixed-point decimal (u8 int/frac, 2-digit precision, 4 bytes).

AncDec32

32-bit fixed-point decimal (u32 int/frac, 9-digit precision, 12 bytes).

AncDec128

128-bit fixed-point decimal (u128 int/frac, 38-digit precision, 40 bytes).

Enums

ParseError

Error returned when parsing a string into a decimal type fails.
