PromoteType< T > Struct Template Reference

Promotion classes which provide an interface for elevating and demoting a scalar or VDB type to a higher or lower precision. Integer types preserve their sign. Types promotion are only valid between 8 to 64 bits (long doubles are not supported). More...

## Detailed Description

template<typename T>
struct openvdb::v12_1::PromoteType< T >

Promotion classes which provide an interface for elevating and demoting a scalar or VDB type to a higher or lower precision. Integer types preserve their sign. Types promotion are only valid between 8 to 64 bits (long doubles are not supported).
