# _mm256_cvttp_epi32

Converts packed float64 values to truncated extended 32-bit integer values. The corresponding Intel® AVX instruction is VCVTTPD2DQ.

## Syntax

extern __m128i _mm256_cvttpd_epi32(__m256d m1);

## Arguments

m1 | float64 source vector

## Description

Converts four packed double-precision floating-point values (float64 values) in the source vector to four packed signed doubleword integer (extended 32-bit integer) values in the destination.

When a conversion is inexact, a truncated (round towards zero) value is returned. If a converted result is larger than the maximum signed doubleword integer, the floating-point invalid exception is raised. If this exception is masked, the indefinite integer value (80000000H) is returned.

## Returns

Result of the conversion operation.
