# vecLibTypes

Create and work with 128-bit vector data types.

## Overview

Overview The vecLibTypes.h header file defines a set of vector data types (vFloat, vUInt32, etc.), which represent 128-bit vectors containing values of type float, UInt32, etc. The vBasicOps.h and vfp.h headers make use of these types. The type names all begin with the letter “v,” followed by a mnemonic for the scalar data type used for elements of the vector. For example, vUInt32, vSInt16, vFloat, etc.
