Implementations

impl MathConstant

pub fn to_f64(self) -> f64

Get the approximate floating-point value of the constant

Examples

use mathhook_core::MathConstant;

assert!((MathConstant::Pi.to_f64() - std::f64::consts::PI).abs() < 1e-10);
assert!((MathConstant::E.to_f64() - std::f64::consts::E).abs() < 1e-10);

Trait Implementations

impl Clone for MathConstant

fn clone(&self) -> MathConstant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MathConstant

impl Debug for MathConstant

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MathConstant

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MathConstant

fn eq(&self, other: &MathConstant) -> 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.

impl Serialize for MathConstant

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
