fasttrig 0.1.6

Fast sine/cosine/tangent approximation using fourth degree polynomials

fasttrig

Requires Numba for optimal performance.

A fast and lightweight approximation of sin, cos, and tan using 4th-degree polynomials.

Unit: radian

Accuracy: Error < 0.001

Important: Numba is required for fasttrig to achieve high performance. Without Numba, performance will be even slower than NumPy. With Numba, the efficiency can be 1.5 to 3.0 times NumPy.

Example

import fasttrig
import numpy as np


x = np.linspace(-np.pi, np.pi, 1000000)

y = fasttrig.sin(x)
c = fasttrig.cos(x)
t = fasttrig.tan(x)
#Scalar
z = fasttrig.sin(1902.0808)
