Struct fixed_decimal::scientific::ScientificDecimal
source · pub struct ScientificDecimal {
significand: FixedDecimal,
exponent: FixedInteger,
}
Expand description
A struct containing a FixedDecimal
significand together with an exponent, representing a
number written in scientific notation, such as 1.729×10³.
This structure represents any 0s shown in the significand and exponent,
and an optional sign for both the significand and the exponent.

ScientificDecimal::from(
FixedDecimal::from(1729).multiplied_pow10(-3),
FixedInteger::from(3)
),

source§fn write_to<W: Write + ?Sized>(&self, sink: &mut W) -> Result
fn write_to<W: Write + ?Sized>(&self, sink: &mut W) -> Result
Writes a string to the given sink. Errors from the sink are bubbled up.
The default implementation delegates to
write_to_parts
, and discards any
Part
annotations.source§fn writeable_length_hint(&self) -> LengthHint
fn writeable_length_hint(&self) -> LengthHint
Returns a hint for the number of UTF-8 bytes that will be written to the sink. Read more

fn write_to_parts<S>(&self, sink: &mut S) -> Result<(), Error>where
S: PartsWrite + ?Sized,
Write bytes and
Part
annotations to the given sink. Errors from the
sink are bubbled up. The default implementation delegates to write_to
,
and doesn’t produce any Part
annotations.impl StructuralPartialEq for ScientificDecimal
