High precision decimal with maximum precision of 38. //! //! ## Optional features //! //! ### `serde` //! //! When this optional dependency is enabled, `Decimal` implements the `serde::Serialize` and //! `serde::Deserialize` traits. //! //! ## Usage //! //! To build a decimal, use [`Decimal`]: //! //! ``` //! use decimal_rs::Decimal; //! //! let n1: Decimal = "123".parse().unwrap(); //! let n2: Decimal = "456".parse().unwrap(); //! let result = n1 + n2; //! assert_eq!(result.to_string(), "579"); //! ``` //! //! To build a decimal from Rust primitive types: //! //! ``` //! use decimal_rs::Decimal; //! //! let n1 = Decimal::from(123_i32); //! let n2 = Decimal::from(456_i32); //! let result = n1 + n2; //! assert_eq!(result, Decimal::from(579_i32)); //! ``` //! //! Decimal supports high precision arithmetic operations. //! //! ``` //! use decimal_rs::Decimal; //! //! let n1: Decimal = "123456789.987654321".parse().unwrap(); //! let n2: Decimal = "987654321.123456789".parse().unwrap(); //! let result = n1 * n2; //! assert_eq!(result.to_string(), "121932632103337905.662094193112635269"); //! ``` //! //! Decimal can be encoded to bytes and decoded from bytes. //! //! ``` //! use decimal_rs::Decimal; //! //! let n1 = "123456789.987654321".parse::<Decimal>().unwrap(); //! let mut bytes = Vec::new(); //! n1.encode(&mut bytes).unwrap(); //! let n2 = Decimal::decode(&bytes); //! assert_eq!(n1, n2); //! ``` // mod buf; mod convert; mod decimal; mod error; mod ops; mod parse; mod u256; #[cfg(feature = "serde")] mod serde; pub use crate::decimal::{Decimal, MAX_BINARY_SIZE, MAX_PRECISION}; pub use crate::error::{DecimalConvertError, DecimalParseError};
