Implementations

impl Ring360

Methods

pub const BASE: f64 = 360f64

The base is 360.0. All degree values will be modulated by this number

pub fn from_gis(lng180: f64) -> Ring360

Alternative constructor if the source degree uses the ±180º GIS system This will not affect the degree conversion, but only the initial rotations value, e.g. (-20).

pub fn degrees(&self) -> f64

Degrees as 64-bit floats on the 0º to 360º scale around a circle Use value() for the intrinsic value that may extend beyond this range

pub fn to_f64(&self) -> f64

Alias for for .degrees(), but is the default f64 conversion

pub fn to_gis(&self) -> f64

Convert the internal 0-360º scale back to the -180º to +180º GIS scale

pub fn rotations(&self) -> i64

Get the number of rotations. If the total is less than base of 360

pub fn progress(&self) -> f64

Get the intrinsic raw value as a decimal fraction of rotations e.g. 180.0 translates to 0.5 and 450.0 to 1.25

pub fn value(&self) -> f64

Returns the raw internal f64 value on a 0-360º scale. Values under 0 or over 360 represent negative or positive rotations

pub fn half_turn() -> f64

pub fn minus_half_turn() -> f64

pub fn as_tuple(&self) -> (f64, i64)

Return a simple tuple pair with the 360º degree value and the number of rotations (turns)

pub fn multiply(self, multiple: f64) -> Self

Multiply a Ring360 value by a normal f64 value

pub fn divide(self, divisor: f64) -> Self

Divide a Ring360 by a normal f64 value

pub fn angle_f64(&self, other_value: f64) -> f64

Calculate the shortest distance in degrees between a Ring360 value and a float64 representing a degree A positive value represents clockwise movement between the first and second longitude

pub fn angle_f64_abs(&self, other_value: f64) -> f64

Calculate the absolute angle with another 64-bit float in the 0 to 360º system only in a clockwise direction with the 180º to 359.999º representing half to a full turn

pub fn angle(&self, other_value: Ring360) -> f64

Calculate the shortest distance in degrees between two a Ring360 values

pub fn angle_abs(&self, other_value: Ring360) -> f64

Calculate the absolute angle with another Ring360 degree only in a clockwise direction with the 180º to 359.999º representing half to a full turn

pub fn to_radians(&self) -> f64

Convert to radians for use with cos(), sin(), tan(), atan() etc.

pub fn sin(&self) -> f64

Calculate sine in the 360º system without explicity converting to radians

pub fn cos(&self) -> f64

Calculate cosine in the 360º system without explicity converting to radians

pub fn tan(&self) -> f64

Calculate tangent in the 360º system without explicity converting to radians

pub fn asin(&self) -> f64

Calculate inverse cosine in the 360º system without explicity converting to and from radians

pub fn acos(&self) -> f64

Calculate inverse cosine in the 360º system without explicity converting to and from radians

pub fn atan(&self) -> f64

Calculate inverse tangent (arctan, aatan) in the 360º system without explicity converting to radians
