Describes double data type support in the current graphics driver.
Syntax
typedef struct D3D11_FEATURE_DATA_DOUBLES { BOOL DoublePrecisionFloatShaderOps; } D3D11_FEATURE_DATA_DOUBLES;
Members
- DoublePrecisionFloatShaderOps
-
Type: BOOL
-
Specifies whether double types are allowed. If TRUE, double types are allowed; otherwise FALSE. The runtime must set DoublePrecisionFloatShaderOps to TRUE in order for you to use any HLSL shader that is compiled with a double type.
Remarks
If the runtime sets DoublePrecisionFloatShaderOps to TRUE, the hardware and driver support the following Shader Model 5 instructions:
Note If DoublePrecisionFloatShaderOps is TRUE, the hardware and driver do not necessarily support double-precision division.
