Struct bigdecimal::BigDecimal

pub struct BigDecimal { /* fields omitted */ }

A big decimal type.

Methods

impl BigDecimal

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

Creates and initializes a BigDecimal.

fn parse_bytes(buf: &[u8], radix: u32) -> Option<BigDecimal>

Creates and initializes a BigDecimal.

Examples

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

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, digits will be dropped.

Trait Implementations

impl Clone for BigDecimal

fn clone(&self) -> BigDecimal

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
