Function Documentation

◆ compare_reversed_order()

template<typename T , size_t Size>

int blender::fixed_width_int::compare_reversed_order	(	const std::array< T, Size > &	a,
		const std::array< T, Size > &	b )

inline

Definition at line 482 of file BLI_fixed_width_int.hh.

◆ generic_add()

template<typename T , typename T2 , int S>

void blender::fixed_width_int::generic_add	(	T *__restrict	dst,
		const T *	a,
		const T *	b )

inline

Adds two fixed-width-integer together using the standard addition with carry algorithm taught in schools. The main difference is that the digits here are not 0 to 9, but 0 to max(T).

Due to the design of two's-complement numbers, this works for signed and unsigned fixed-width-integer. The overflow behavior is wrap-around.

Parameters

T	Type for individual digits.
T2	Integer type that is twice as large as T.
S	Number of digits of type T in each fixed-width-integer.

◆ is_negative()

template<typename T , int Size>

bool blender::fixed_width_int::is_negative ( const IntF< T, Size > & a )

Using this function is faster than using the comparison operator. Only a single bit has to be checked to determine if the value is negative.
