XMConvertVectorIntToFloat function (directxmath.h)
Converts an XMVECTOR with int32_t components to an XMVECTOR with float components and applies a uniform bias.
XMVECTOR XM_CALLCONV XMConvertVectorIntToFloat( FXMVECTOR VInt, uint32_t DivExponent );
Vector with int32_t components that is to be converted.
Each component of VInt will be converted to a float and then divided by two raised to the DivExponent power. This parameter must be a number (an immediate value) and not a variable.
Returns the converted vector, where each component has been divided by two raised to the DivExponent power.
