Struct bigdecimal::BigDecimal[][src]

pub struct BigDecimal { /* fields omitted */ }

A big decimal type.

Methods

impl BigDecimal
[src]

Creates and initializes a BigDecimal.

Creates and initializes a BigDecimal.

Examples

use bigdecimal::{BigDecimal, Zero};

assert_eq!(BigDecimal::parse_bytes(b"0", 10).unwrap(), BigDecimal::zero());
// assert_eq!(BigDecimal::parse_bytes(b"f", 16), BigDecimal::parse_bytes(b"16", 10));

Return a new BigDecimal object equivalent to self, with internal scaling set to the number specified. If the new_scale is lower than the current value (indicating a larger power of 10), digits will be dropped (as precision is lower)

Return the sign of the BigDecimal as num::bigint::Sign.

Examples

extern crate num;
extern crate bigdecimal;
use std::str::FromStr;

assert_eq!(bigdecimal::BigDecimal::from_str("-1").unwrap().sign(), num::bigint::Sign::Minus);
assert_eq!(bigdecimal::BigDecimal::from_str("0").unwrap().sign(), num::bigint::Sign::NoSign);
assert_eq!(bigdecimal::BigDecimal::from_str("1").unwrap().sign(), num::bigint::Sign::Plus);

Return the internal big integer value and an exponent. Note that a positive exponent indicates a negative power of 10.

Examples

extern crate num;
extern crate bigdecimal;
use std::str::FromStr;

assert_eq!(bigdecimal::BigDecimal::from_str("1.1").unwrap().as_bigint_and_exponent(),
           (num::bigint::BigInt::from_str("11").unwrap(), 1));

Convert into the internal big integer value and an exponent. Note that a positive exponent indicates a negative power of 10.

Examples

extern crate num;
extern crate bigdecimal;
use std::str::FromStr;

assert_eq!(bigdecimal::BigDecimal::from_str("1.1").unwrap().into_bigint_and_exponent(),
           (num::bigint::BigInt::from_str("11").unwrap(), 1));
