1.与运算(AND):用符号"&"表示,对两个操作数的每一位进行逻辑与操作,只有当两个操作数对应的位都为1时,结果位才为1。例如:Result := A AND B; 2.或运算(OR):用符号"|"表示,对两个操作数的每一位进行逻辑或操作,只要两个操作数对应的位中有一个为1,结果位就为1。例如:Result := A OR B; 3....
Delphi 系统[13]关键字和保留字 and、or、not、xor、shl、shr、div、mod1、定义:and(逻辑与 或 按位与) or(逻辑或 或 按位或) not(逻辑非 或 按位否) //Not用于取反, 它否定了原先的结果 xor(逻辑异或 或 按位异或),只要 xor 两边的布尔值不相同(相异),结果就为 True,否则就为 False。只要...
The 64 bit version now uses 64 bit addition where possible (in the main loop and in Main3 and Main2, which are not "fall-through" like above) and before, 64 bit was quite a lot slower than 32 bit, but now it is 30% faster than 32 bit and twice as fast as the origin...

一、在Delphi中$表示后面的数是十六进制数。十六进制数的位从0~F取值,A~F表示十进制的10~15。第N位的权是16^(N-1)。例如:$02=2 $08=8 $10=16 $20=32 $30=48 $100=256 ...二、在Delphi中and表示[位运算]中的“与”。即将两个操作数取其二进制,每一位上的数进行“若是两者皆...
