Implementations

impl Scientific

pub const ZERO: Scientific = _

pub const ONE: Scientific = _

pub fn from_string(source: String) -> Result<Scientific, ConversionError>

pub fn to_bytes(&self) -> Vec<u8>

pub fn from_bytes(bytes: &[u8]) -> Result<Scientific, ConversionError>

pub fn as_raw_mantissa(&self) -> &[u8]

pub fn from_raw_parts( negative: bool, mantissa: Vec<u8>, exponent: isize ) -> Result<Scientific, ConversionError>

pub fn abs(&self) -> Scientific

pub fn abs_assign(&mut self)

pub fn div_truncate( &self, rhs: &Scientific, precision: Precision ) -> Result<Scientific, Error>

Please be aware that div_truncate is only calculating digits up to the specified precision.

For example 509/100 with a precision of 2 digits or 1 decimals will calculate 5.0 and not 5.1 as it’s may be expected with rounding in mind.

pub fn div_rem( &self, rhs: &Scientific ) -> Result<(Scientific, Scientific), Error>

pub fn div_rpsp( &self, rhs: &Scientific, precision: Precision ) -> Result<Scientific, Error>

Calculate division with included rpsp (Rounding to Prepare for Shorter Precision)

Use rpsp (Rounding to Prepare for Shorter Precision) only during internal calculations and do one “proper” round at the end of all calculations.

pub fn truncate_assign(&mut self, precision: Precision)

pub fn truncate(&self, precision: Precision) -> Scientific

pub fn round_assign(&mut self, precision: Precision, rounding: Rounding)

pub fn round(&self, precision: Precision, rounding: Rounding) -> Scientific

pub fn round_rpsp_assign(&mut self, precision: Precision)

pub fn round_rpsp(&self, precision: Precision) -> Scientific

pub fn len(&self) -> isize

pub fn decimals(&self) -> isize

pub fn exponent0(&self) -> isize

pub fn exponent1(&self) -> isize

pub fn exponent(&self) -> isize

pub fn powi(&self, exponent: usize) -> Scientific

pub fn is_sign_positive(&self) -> bool

Returns true if self has a positive sign, this excludes 0.

Returns true if self has a negative sign, this excludes 0.
