utof (sm4 - asm)
Unsigned integer to floating point conversion.
|utof dest[.mask], src0[.swizzle]|
[in] The address of the result of the operation.
[in] The components to convert.
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|
