Trigonometric functions

template<class B>
batch_type_t<B> xsimd::sin(const simd_base<B> &x)

Computes the sine of the batch x.

Return

the sine of x.

Parameters

• x: batch of floating point values.

template<class B>
batch_type_t<B> xsimd::cos(const simd_base<B> &x)

Computes the cosine of the batch x.

Return

the cosine of x.

Parameters

• x: batch of floating point values.

template<class B>
void xsimd::sincos(const simd_base<B> &x, batch_type_t<B> &si, batch_type_t<B> &co)

Computes the sine and the cosine of the batch x.

This method is faster than calling sine and cosine independently.

Parameters

• x: batch of floating point values.

• si: the sine of x.

• co: the cosine of x.

template<class B>
batch_type_t<B> xsimd::tan(const simd_base<B> &x)

Computes the tangent of the batch x.

Return

the tangent of x.

Parameters

• x: batch of floating point values.

template<class B>
batch_type_t<B> xsimd::asin(const simd_base<B> &x)

Computes the arc sine of the batch x.

Return

the arc sine of x.

Parameters

• x: batch of floating point values.

template<class B>
batch_type_t<B> xsimd::acos(const simd_base<B> &x)

Computes the arc cosine of the batch x.

Return

the arc cosine of x.

Parameters

• x: batch of floating point values.

template<class B>
batch_type_t<B> xsimd::atan(const simd_base<B> &x)

Computes the arc tangent of the batch x.

Return

the arc tangent of x.

Parameters

• x: batch of floating point values.

template<class B>
batch_type_t<B> xsimd::atan2(const simd_base<B> &y, const simd_base<B> &x)

Computes the arc tangent of the batch x/y, using the signs of the arguments to determine the correct quadrant.

Return

the arc tangent of x/y.

Parameters

• x: batch of floating point values.

• y: batch of floating point values.
