utof (sm4 - asm)
Unsigned integer to floating point conversion.
| utof dest[.mask], src0[.swizzle] |
|---|
| Item | Description |
|---|---|
| dest |
[in] The address of the result of the operation. |
| src0 |
[in] The components to convert. |
Remarks
src0 must contain an unsigned 32-bit integer 4-tuple. After the instruction executes, dest will contain a floating-point 4-tuple. The conversion is performed per-component.
When an integer input value is too large to be represented exactly in the floating point format, round to nearest even mode.
This instruction applies to the following shader stages:
| Vertex Shader | Geometry Shader | Pixel Shader |
