XMFLOAT3SE::operator uint32_t function (directxpackedvector.h)

  • Article

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.
