Overload Details

Overload 1

function ReflectPow2(Value, Max: Integer): Integer; overload;

Reflects an integer value in range [0..Max] where Max+1 is a power of two.

Parameter	Type	Description
Value	Integer	Integer value to reflect.
Max	Integer	Inclusive upper bound (where Max+1 is a power of 2).

Type	Description
Integer	Reflected integer coordinate in range [0..Max].

Overload 2

function ReflectPow2(Value, Min, Max: Integer): Integer; overload;

Reflects an integer value in range [Min..Max] where Max-Min+1 is a power of two.

Parameter	Type	Description
Value	Integer	Integer value to reflect.
Min	Integer	Inclusive lower bound.
Max	Integer	Inclusive upper bound (where Max-Min+1 is a power of 2).

Type	Description
Integer	Reflected integer coordinate in range [Min..Max].

Description

ReflectPow2 provides optimized power-of-two reflection by utilizing bitwise operations instead of division and modulo instructions.
