# _mm_hypot_pd, _mm256_hypot_pd

Computes the length of the hypotenuse of a right angled triangle. Vector variant of hypot(x) function for a 128-bit/256-bit vector argument of float64 values.

## Syntax

extern __m128d _mm_hypot_pd(__m128d v1, __m128d v2);

extern __m256d _mm256_hypot_pd(__m256d v1, __m256d v2);

## Arguments

v1 | vector with float64 values
v2 | vector with float64 values

## Description

Computes the length of the hypotenuse of a right angled triangle with sides v1 and v2, defined by:

    sqrt (v12 + v22)

## 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.
