XMFLOAT3PK::operator=(uint32_t) function (directxpackedvector.h)

  • Article

This operator assigns the vector component data packed in an instance of uint32_t to the current instance of XMFLOAT3PK.

Note  This operator is only available under C++.
 

Syntax

XMFLOAT3PK & operator=(
  uint32_t Packed
) noexcept;

Parameters

Packed

The values of three vector components in a packed format.

Return value

The current instance of XMFLOAT3PK whose vector component data has been updated to the component values packed in the uint32_t instance specified by the Packed argument.

Remarks

The values of the three components assigned to the current instance of XMFLOAT3PK are stored in the argument Packed with the z component (as a reduced precision floating point number) in the most significant bits, and the x component is stored in the least significant bits:

  (Z10Y11X11): [32] ZZZZZzzz zzYYYYYy yyyyyXXX XXxxxxxx [0]
Or in detail:
  • Bits 0-5 of v are the 6 bit mantissa of the x component's floating point value: the xm member of the current structure.
  • Bits 6-10 of v are the 5 bit exponent of the x component's floating point value the xe member of the current structure.
  • Bits 11-16 of v are the 6-bit mantissa of the y component's floating point value: the ym member of the current structure.
  • Bits 17-21 of v are the 5 bit exponent of the y component's floating point value: the ye member of the current structure.
  • Bits 22-26 of v are the 5 bit mantissa of the z component's floating point value: the zm member of the current structure.
  • Bits 27-31 of v are the 5 bit exponent of the z component's floating point value: the ze member of the current structure.
