Implementations

impl PolarCoordinates

pub fn to_rectangular_coordinates(&self) -> RectangularCoordinates

Converts from polar to rectangular coordinates

Examples

use com_croftsoft_core::math::math_lib::*;
assert_eq!(
  PolarCoordinates {
    angle: 0.0,
    radius: 1.0,
  }.to_rectangular_coordinates(),
  RectangularCoordinates {
    x: 1.0,
    y: 0.0,
  });
assert_eq!(
  PolarCoordinates {
    angle: std::f64::consts::FRAC_PI_2,
    radius: 1.0,
  }.to_rectangular_coordinates(),
  RectangularCoordinates {
    x: 6.123233995736766e-17,
    y: 1.0,
  });
assert_eq!(
  PolarCoordinates {
    angle: std::f64::consts::PI,
    radius: 1.0,
  }.to_rectangular_coordinates(),
  RectangularCoordinates {
    x: -1.0,
    y: 1.2246467991473532e-16,
  });
assert_eq!(
  PolarCoordinates {
    angle: 3.0 * std::f64::consts::FRAC_PI_2,
    radius: 2.0,
  }.to_rectangular_coordinates(),
  RectangularCoordinates {
    x: -3.6739403974420594e-16,
    y: -2.0,
  });

Trait Implementations

impl Clone for PolarCoordinates

fn clone(&self) -> PolarCoordinates

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PolarCoordinates

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

Formats the value using the given formatter.

impl PartialEq<PolarCoordinates> for PolarCoordinates

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

This method tests for self and other values to be equal, and is used by ==.

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

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