XMFLOAT3PK::operator uint32_t function (directxpackedvector.h)

  • Article

Returns an instance of uint32_t containing the components of the XMFLOAT3PK instance in a packed format.

This operator returns an instance of uint32_t containing the components of the XMFLOAT3PK 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 XMFLOAT3PK in a packed format.

Remarks

The values of the three components of the current instance of XMFLOAT3PK are returned packed in a uint32_t 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 the return value are the 6 bit mantissa of the x component's floating point value.
  • Bits 6-10 of the return value are the 5 bit exponent of the x component's floating point value.
  • Bits 11-16 of the return value are the 6-bit mantissa of the y component's floating point value.
  • Bits 17-21 of the return value are the 5 bit exponent of the y component's floating point value.
  • Bits 22-26 of the return value are the 5 bit mantissa of the z component's floating point value.
  • Bits 27-31 of the return value are the 5 bit exponent of the z component's floating point value.
