Expand description
A big decimal type.
Implementations§
§impl BigDecimal
impl BigDecimal
pub fn new(digits: BigInt, scale: i64) -> BigDecimal
pub fn new(digits: BigInt, scale: i64) -> BigDecimal
Creates and initializes a BigDecimal
.
pub fn parse_bytes(buf: &[u8], radix: u32) -> Option<BigDecimal>
pub fn parse_bytes(buf: &[u8], radix: u32) -> Option<BigDecimal>
Creates and initializes a BigDecimal
.
Decodes using str::from_utf8
and forwards to BigDecimal::from_str_radix
.
Only base-10 is supported.
§Examples
use bigdecimal::{BigDecimal, Zero};
assert_eq!(BigDecimal::parse_bytes(b"0", 10).unwrap(), BigDecimal::zero());
assert_eq!(BigDecimal::parse_bytes(b"13", 10).unwrap(), BigDecimal::from(13));
pub fn with_scale(&self, new_scale: i64) -> BigDecimal
pub fn with_scale(&self, new_scale: i64) -> BigDecimal
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)
pub fn with_prec(&self, prec: u64) -> BigDecimal
pub fn with_prec(&self, prec: u64) -> BigDecimal
Return a new BigDecimal object with precision set to new value
pub fn sign(&self) -> Sign
pub fn sign(&self) -> Sign
Return the sign of the BigDecimal
as num::bigint::Sign
.
§Examples
extern crate num_bigint;
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);
pub fn as_bigint_and_exponent(&self) -> (BigInt, i64)
pub fn as_bigint_and_exponent(&self) -> (BigInt, i64)
Return the internal big integer value and an exponent. Note that a positive exponent indicates a negative power of 10.
§Examples
extern crate num_bigint;
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));
pub fn into_bigint_and_exponent(self) -> (BigInt, i64)
pub fn into_bigint_and_exponent(self) -> (BigInt, i64)
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_bigint;
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));
pub fn abs(&self) -> BigDecimal
pub fn abs(&self) -> BigDecimal
Compute the absolute value of number
pub fn double(&self) -> BigDecimal
pub fn half(&self) -> BigDecimal
pub fn half(&self) -> BigDecimal
Divide this efficiently by 2
Note, if this is odd, the precision will increase by 1, regardless of the context’s limit.
pub fn square(&self) -> BigDecimal
pub fn square(&self) -> BigDecimal
pub fn cube(&self) -> BigDecimal
pub fn sqrt(&self) -> Option<BigDecimal>
pub fn sqrt(&self) -> Option<BigDecimal>
Take the square root of the number
If the value is < 0, None is returned
pub fn cbrt(&self) -> BigDecimal
pub fn cbrt(&self) -> BigDecimal
Take the cube root of the number
pub fn inverse(&self) -> BigDecimal
pub fn inverse(&self) -> BigDecimal
Compute the reciprical of the number: x-1
pub fn round(&self, round_digits: i64) -> BigDecimal
pub fn round(&self, round_digits: i64) -> BigDecimal
Return number rounded to round_digits precision after the decimal point
pub fn is_integer(&self) -> bool
pub fn is_integer(&self) -> bool
Return true if this number has zero fractional part (is equal to an integer)
pub fn exp(&self) -> BigDecimal
pub fn exp(&self) -> BigDecimal
Evaluate the natural-exponential function ex
pub fn normalized(&self) -> BigDecimal
