The HasDoubleSupport checks if a CUDA-enabled device supports double precision computation and returns true or false.  Certain Maple routines require a CUDA-enabled device capable of double precision computation.

CUDA-enabled devices are enumerated so that each device is assigned a unique number. The id parameter allows you to select the device for which you want to view properties. If the id parameter is not specified, a table with the id as the index and true or false as the entry.

$\mathrm{CUDA}:-\mathrm{Enable}\left(\mathrm{true}\right)$

$\mathrm{false}$

$\mathrm{CUDA}:-\mathrm{HasDoubleSupport}\left(\right)$

$\mathrm{table}\left(\left[0=\mathrm{true}\right]\right)$

$\mathrm{CUDA}:-\mathrm{HasDoubleSupport}\left(\mathrm{id}=0\right)$

$\mathrm{true}$

The CUDA[HasDoubleSupport] command was introduced in Maple 15.
