C++ (Cpp) CountLeadingZeros Examples

Example #1

File: CheckCLZL.c Project: brown722/FHE-BGV

int main()
{
   unsigned long x = 3;
   touch(x);
   if (CountLeadingZeros(x) == NTL_BITS_PER_LONG-2)
      return 0;
   else
      return -1;
}

Example #2

File: bitbuf.cpp Project: xxauroraxx/Source.Python

inline unsigned int BitCountNeededToEncode(unsigned int data)
{
#if defined(_X360)
	return (32 - CountLeadingZeros(data+1)) - 1;
#else
	unsigned long firstBit;
	_BitScanReverse(&firstBit,data+1);
	return firstBit;
#endif
}

Example #3

File: Shader.cpp Project: droidenko/dava.framework

int32 Shader::GetAttributeIndex(eVertexFormat vertexFormat)
{
    return vertexFormatAttribIndeces[CountLeadingZeros(vertexFormat)];
}
