Implementations

impl FixedDecimal

pub fn from_int32(v: i32) -> Box<FixedDecimal>

Construct an FixedDecimal from an integer.

pub fn from_uint32(v: u32) -> Box<FixedDecimal>

Construct an FixedDecimal from an integer.

pub fn from_int64(v: i64) -> Box<FixedDecimal>

Construct an FixedDecimal from an integer.

pub fn from_uint64(v: u64) -> Box<FixedDecimal>

Construct an FixedDecimal from an integer.

pub fn from_double_with_integer_precision( f: f64, ) -> Result<Box<FixedDecimal>, FixedDecimalLimitError>

Construct an FixedDecimal from an integer-valued float

pub fn from_double_with_lower_magnitude( f: f64, magnitude: i16, ) -> Result<Box<FixedDecimal>, FixedDecimalLimitError>

Construct an FixedDecimal from an float, with a given power of 10 for the lower magnitude

pub fn from_double_with_significant_digits( f: f64, digits: u8, ) -> Result<Box<FixedDecimal>, FixedDecimalLimitError>

Construct an FixedDecimal from an float, for a given number of significant digits

pub fn from_double_with_round_trip_precision( f: f64, ) -> Result<Box<FixedDecimal>, FixedDecimalLimitError>

Construct an FixedDecimal from an float, with enough digits to recover the original floating point in IEEE 754 without needing trailing zeros

pub fn from_string( v: &DiplomatStr, ) -> Result<Box<FixedDecimal>, FixedDecimalParseError>

Construct an FixedDecimal from a string.

pub fn digit_at(&self, magnitude: i16) -> u8

pub fn magnitude_start(&self) -> i16

pub fn magnitude_end(&self) -> i16

pub fn nonzero_magnitude_start(&self) -> i16

pub fn nonzero_magnitude_end(&self) -> i16

pub fn is_zero(&self) -> bool

pub fn multiply_pow10(&mut self, power: i16)

Multiply the FixedDecimal by a given power of ten.

pub fn sign(&self) -> FixedDecimalSign

pub fn set_sign(&mut self, sign: FixedDecimalSign)

Set the sign of the FixedDecimal.

pub fn apply_sign_display(&mut self, sign_display: FixedDecimalSignDisplay)

pub fn trim_start(&mut self)

pub fn trim_end(&mut self)

pub fn pad_start(&mut self, position: i16)

Zero-pad the FixedDecimal on the left to a particular position

pub fn pad_end(&mut self, position: i16)

Zero-pad the FixedDecimal on the right to a particular position

pub fn set_max_position(&mut self, position: i16)

Truncate the FixedDecimal on the left to a particular position, deleting digits if necessary. This is useful for, e.g. abbreviating years (“2022” -> “22”)

pub fn round(&mut self, position: i16)

Round the number at a particular digit position.

This uses half to even rounding, which resolves ties by selecting the nearest even integer to the original value.

pub fn ceil(&mut self, position: i16)

pub fn expand(&mut self, position: i16)

pub fn floor(&mut self, position: i16)

pub fn trunc(&mut self, position: i16)

pub fn round_with_mode(&mut self, position: i16, mode: FixedDecimalRoundingMode)

pub fn round_with_mode_and_increment( &mut self, position: i16, mode: FixedDecimalRoundingMode, increment: FixedDecimalRoundingIncrement, )

pub fn concatenate_end(&mut self, other: &mut FixedDecimal) -> Result<(), ()>

Concatenates other to the end of self.

If successful, other will be set to 0 and a successful status is returned.

If not successful, other will be unchanged and an error is returned.

pub fn to_string(&self, to: &mut DiplomatWrite)

Format the FixedDecimal as a string.
