normalize(a, center)
🍋
(Adapted from Apach Commons normalizeAngle, MathUtils sources) Normalize an angle in a 2pi; wide interval around a center value.
This method has three main uses:
- normalize an angle between 0 and 2pi: a = normalize(a, np.pi)
- normalize an angle between -pi and +pi: a = normalize(a, 0.0)
- compute the angle between two defining angular positions: angle = normalize(end, start) - start
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
a |
float
|
angle to be normalized (in radians). |
required |
center |
float
|
center value in radians. |
required |
Returns:
| Type | Description |
|---|---|
float
|
normalized angle in radians. |
Example
import geolime as geo
import numpy as np
geo.normalize(np.pi / 2, 2 * np.pi)
Output
7.853981633974483
Info
Due to numerical accuracy and since pi cannot be represented exactly, the result interval is closed, it cannot be half-closed as would be more satisfactory in a purely mathematical view.
