# _mm_cmp_ss

Compares scalar float32 values. The corresponding Intel® AVX instruction is VCMPSS.

## Syntax

extern __m128 _mm_cmp_ss(__m128 m1, __m128 m2, const int predicate);

## Arguments

m1 | float32 vector used for the operation
m2 | float32 vector also used for the operation
predicate | an immediate operand that specifies the type of comparison to be performed of the packed values; see immintrin.h file for the values to specify the type of comparison

## Description

Performs a compare operation of the low single-precision floating-point values (float32 values) in the first source operand, m1, and the second source operand, m2, and returns the results.

The comparison predicate parameter (immediate) specifies the type of comparison performed.

## Returns

Result of the compare operation.
