# _mm_cosh_pd, _mm256_cosh_pd

Calculates the hyperbolic cosine value. Vector variant of cosh(x) function for a 128-bit/256-bit vector argument of float64 values.

## Syntax

extern __m128d _mm_cosh_pd(__m128d v1, __m128d v2);

extern __m256d _mm256_cosh_pd(__m256d v1);

## Arguments

v1 | vector with float64 values

## Description

Calculates the hyperbolic cosine of vector v1 elements, which is defined mathematically as:

    (exp(x) + exp(-x)) / 2

## Returns

128-bit/256-bit vector with the result of the operation.

### Note

Many routines in the Short Vector Math Library (SVML) are more optimized for Intel® microprocessors than for non-Intel microprocessors.
