A big decimal type.

Implementations

impl BigDecimal

pub fn new(digits: BigInt, scale: i64) -> BigDecimal

Creates and initializes a BigDecimal.

The more explicit method from_bigint should be preferred, as new may change in the future.

pub fn from_bigint(digits: BigInt, scale: i64) -> BigDecimal

Construct BigDecimal from BigInt and a scale

pub fn from_biguint(digits: BigUint, scale: i64) -> BigDecimal

Construct positive BigDecimal from BigUint and a scale

pub fn to_ref(&self) -> BigDecimalRef<'_>

Make a BigDecimalRef of this value

pub fn decimal_digit_count(&self) -> u64

Count of decimal digits

Zero is considered to be one digit.

pub fn order_of_magnitude(&self) -> i64

Position of most significant digit of this decimal

Equivalent to the exponent when written in scientific notation, or ⌊log10(n)⌋.

The order of magnitude of 0 is 0.

pub fn fractional_digit_count(&self) -> i64

Returns the scale of the BigDecimal, the total number of digits to the right of the decimal point (including insignificant leading zeros)

Examples

use bigdecimal::BigDecimal;
use std::str::FromStr;

let a = BigDecimal::from(12345);  // No fractional part
let b = BigDecimal::from_str("123.45").unwrap();  // Fractional part
let c = BigDecimal::from_str("0.0000012345").unwrap();  // Completely fractional part
let d = BigDecimal::from_str("5e9").unwrap();  // Negative-fractional part

assert_eq!(a.fractional_digit_count(), 0);
assert_eq!(b.fractional_digit_count(), 2);
assert_eq!(c.fractional_digit_count(), 10);
assert_eq!(d.fractional_digit_count(), -9);

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

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_scale_round(&self, new_scale: i64, mode: RoundingMode) -> BigDecimal

Return a new BigDecimal after shortening the digits and rounding

let n: BigDecimal = "129.41675".parse().unwrap();

assert_eq!(n.with_scale_round(-1, RoundingMode::Down),  "120".parse().unwrap());
assert_eq!(n.with_scale_round(4, RoundingMode::HalfEven),  "129.4168".parse().unwrap());

pub fn with_prec(&self, prec: u64) -> BigDecimal

Return a new BigDecimal object with precision set to new value

let n: BigDecimal = "129.41675".parse().unwrap();

assert_eq!(n.with_prec(2),  "130".parse().unwrap());

let n_p12 = n.with_prec(12);
let (i, scale) = n_p12.as_bigint_and_exponent();
assert_eq!(n_p12, "129.416750000".parse().unwrap());
assert_eq!(i, 129416750000_u64.into());
assert_eq!(scale, 9);

pub fn with_precision_round( &self, prec: NonZero<u64>, round: RoundingMode, ) -> BigDecimal

Return this BigDecimal with the given precision, rounding if needed

pub fn sign(&self) -> Sign

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

fn sign_of(src: &str) -> Sign {
   let n: BigDecimal = src.parse().unwrap();
   n.sign()
}

assert_eq!(sign_of("-1"), Sign::Minus);
assert_eq!(sign_of("0"),  Sign::NoSign);
assert_eq!(sign_of("1"),  Sign::Plus);

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

use bigdecimal::{BigDecimal, num_bigint::BigInt};

let n: BigDecimal = "1.23456".parse().unwrap();
let expected = ("123456".parse::<BigInt>().unwrap(), 5);
assert_eq!(n.as_bigint_and_exponent(), expected);

pub fn into_bigint_and_scale(self) -> (BigInt, i64)

Take BigDecimal and split into num::BigInt of digits, and the scale

Scale is number of digits after the decimal point, can be negative.

pub fn as_bigint_and_scale(&self) -> (Cow<'_, BigInt>, i64)

Return digits as borrowed Cow of integer digits, and its scale

Scale is number of digits after the decimal point, can be negative.

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

use bigdecimal::{BigDecimal, num_bigint::BigInt};

let n: BigDecimal = "1.23456".parse().unwrap();
let expected = ("123456".parse::<num_bigint::BigInt>().unwrap(), 5);
assert_eq!(n.into_bigint_and_exponent(), expected);

Note: If the last digit in the decimal is odd, the precision will increase by 1

let n: BigDecimal = "123.45".parse().unwrap();
assert_eq!(n.half(), "61.725".parse().unwrap());

pub fn square(&self) -> BigDecimal

Square a decimal: x²

No rounding or truncating of digits; this is the full result of the squaring operation.

Note: doubles the scale of bigdecimal, which might lead to accidental exponential-complexity if used in a loop.

let n: BigDecimal = "1.1156024145937225657484".parse().unwrap();
assert_eq!(n.square(), "1.24456874744734405154288399835406316085210256".parse().unwrap());

let n: BigDecimal = "-9.238597585E+84".parse().unwrap();
assert_eq!(n.square(), "8.5351685337567832225E+169".parse().unwrap());

Note: triples the scale of bigdecimal, which might lead to accidental exponential-complexity if used in a loop.

let n: BigDecimal = "1.1156024145937225657484".parse().unwrap();
assert_eq!(n.cube(), "1.388443899780141911774491376394890472130000455312878627147979955904".parse().unwrap());

Return given number rounded to ‘round_digits’ precision after the decimal point, using default rounding mode

Default rounding mode is HalfEven, but can be configured at compile-time by the environment variable: RUST_BIGDECIMAL_DEFAULT_ROUNDING_MODE (or by patching build.rs )

pub fn is_integer(&self) -> bool

Return true if this number has zero fractional part (is equal to an integer)

pub fn is_one_quickcheck(&self) -> Option<bool>

Try to determine if decimal is 1.0, without allocating

pub fn exp(&self) -> BigDecimal

Evaluate the natural-exponential function e^x

pub fn normalized(&self) -> BigDecimal

pub fn to_plain_string(&self) -> String

Create string of decimal in standard decimal notation.

Unlike standard formatter, this never prints the number in scientific notation.

Panics

If the magnitude of the exponent is very large, this may cause out-of-memory errors, or overflowing panics.

Examples

let n: BigDecimal = "123.45678".parse().unwrap();
assert_eq!(&n.to_plain_string(), "123.45678");

let n: BigDecimal = "1e-10".parse().unwrap();

pub fn write_plain_string<W>(&self, wtr: &mut W) -> Result<(), Error>

where W: Write,

Write decimal value in decimal notation to the writer object.

Panics

If the exponent is very large or very small, the number of this will print that many trailing or leading zeros. If exabytes, this will likely panic.

pub fn to_scientific_notation(&self) -> String

Create string of this bigdecimal in scientific notation

let n = BigDecimal::from(12345678);
assert_eq!(&n.to_scientific_notation(), "1.2345678e7");

where W: Write,

Write bigdecimal in scientific notation to writer w

pub fn to_engineering_notation(&self) -> String

Engineering notation is scientific notation with the exponent coerced to a multiple of three

let n = BigDecimal::from(12345678);
assert_eq!(&n.to_engineering_notation(), "12.345678e6");

pub fn write_engineering_notation<W>(&self, w: &mut W) -> Result<(), Error>

where W: Write,

Write bigdecimal in engineering notation to writer w

fn size_hint(&self) -> usize

impl Encode<'_, Postgres> for BigDecimal

Note: BigDecimal Has a Larger Range than NUMERIC

BigDecimal can represent values with a far, far greater range than the NUMERIC type in Postgres can.

NUMERIC is limited to 131,072 digits before the decimal point, and 16,384 digits after it. See Section 8.1, Numeric Types of the Postgres manual for details.

Meanwhile, BigDecimal can theoretically represent a value with an arbitrary number of decimal digits, albeit with a maximum of 2⁶³ significant figures.

Because encoding in the current API design must be infallible, when attempting to encode a BigDecimal that cannot fit in the wire representation of NUMERIC, SQLx may instead encode a sentinel value that falls outside the allowed range but is still representable.

This will cause the query to return a DatabaseError with code 22P03 (invalid_binary_representation) and the error message invalid scale in external "numeric" value (though this may be subject to change).

However, BigDecimal should be able to decode any NUMERIC value except NaN, for which it has no representation.
