Enum Value 

pub enum Value {
    Integer(i64),
    Rational(Rational64),
    Float(f64),
    Complex(f64, f64),
    PositiveInfinity,
    NegativeInfinity,
    NaN,
}

Value representation with precision information.

Variants

Integer(i64)

Exact integer value.

Rational(Rational64)

Exact rational value (fraction).

Float(f64)

Floating-point value.

Complex(f64, f64)

Complex value (real, imaginary).

PositiveInfinity

Positive infinity.

NegativeInfinity

Negative infinity.

NaN

Not a number.

Implementations

impl Value

pub fn as_f64(&self) -> f64

Convert value to f64, if possible.

pub fn is_finite(&self) -> bool

Check if value is finite.

pub fn is_real(&self) -> bool

Check if value is real (not complex with imaginary part).

pub fn is_nan(&self) -> bool

Check if value is NaN.

pub fn is_zero(&self) -> bool

Check if value is zero.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Value

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Value

fn eq(&self, other: &Value) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
