XMFLOAT3SE::operator uint32_t function (directxpackedvector.h)
Returns an instance of uint32_t containing the components of the
XMFLOAT3SE instance in a packed format.
This operator returns an instance of uint32_t containing the components of the
XMFLOAT3SE instance in a packed format.
Note This operator is only available under C++.
Syntax
void operator uint32_t() noexcept;
Return value
Contains the three vector components of an instance of XMFLOAT3SE in a packed format.
Remarks
The values of the three components of the current instance of XMFLOAT3SE are
returned in the following format: the e member of the XMFLOAT3SE structure -- the exponent shared by the mantissas of the floating point values of all
three components of XMFLOAT3SE -- is stored in the highest order bits of the
return value, and the mantissa of the x component stored in the least significant bits.
(E5Z9Y9X9): [32] EEEEEzzz zzzzzzyy yyyyyyyx xxxxxxxx [0]
Or in detail:
- Bits 0-8 of the return value are the 9 bit mantissa of the x component's floating point value: the xm member of the current structure.
- Bits 9-17 of the return value are the 9 bit mantissa of the y component's floating point value: the ym member of the current structure.
- Bits 18-26 of the return value are the 9 bit mantissa of the z component's floating point value: the zm member of the current structure.
- Bits 27-31 of the return value are the 5 bit exponent used with the stored mantissas (xm, ym, zm) to represent the size of each component: the e member of the current structure.
