libm-ext

A Python package wrapping the essential mathematical special functions in libm-ext with vectorized support.

Trigonometric functions

• sinpi / sinpif for $\sin(\pi x)$ (double-precision / single-precision)
• cospi / cospif for $\cos(\pi x)$ (double-precision / single-precision)
• sincospi / sincospif for $\sin(\pi x)$ and $\cos(\pi x)$ (double-precision / single-precision)

Usage

Scalar functions

from libm_ext import sinpi, cospi, sincospi

sinpi(1.0)
cospi(1.0)
sincospi(1.0)

Vectorized functions with NumPy ndarray

import numpy as np
from libm_ext.vectorized import sinpi, cospi

x = np.random.standard_normal(16000)
sinpi(x)
cospi(x)
