Scalar types

The fundamental C++ data types which are supported in SYCL are described in SYCL Specification Table 179. Note these types are fundamental and therefore do not exist within the sycl namespace.

Additional scalar data types which are supported by SYCL within the sycl namespace are described below :

Scalar data types

sycl::byte

An unsigned 8-bit integer. This is deprecated in SYCL 2020 since C++17 std::byte can be used instead.

sycl::half

A 16-bit floating-point type. The half data type must conform to the IEEE 754-2008 half precision storage format. This type is only supported on devices that have aspect::fp16. std::numeric_limits must be specialized for the half data type.
