# vecLibTypes

Create and work with 128-bit vector data types.

## Discussion

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.
