名称:| (bitwise OR)
例子:
int a = 205; // In binary: 11001101 int b = 45; // In binary: 00101101 int c = a | b; // In binary: 11101101 println(c); // Prints "237", the decimal equivalent to 11101101
int a = 255 << 24; // Binary: 11111111000000000000000000000000 int r = 204 << 16; // Binary: 00000000110011000000000000000000 int g = 204 << 8; // Binary 00000000000000001100110000000000 int b = 51; // Binary: 00000000000000000000000000110011 // OR the values together: 11111111110011001100110000110011 color argb = a | r | g | b; fill(argb); rect(30, 20, 55, 55);
描述:
Compares each corresponding bit in the binary representation of the values. For each comparison two 1’s yield 1, 1 and 0 yield 1, and two 0’s yield 0. This is easy to see when we look at the binary representation of numbers
比较二进制表示的值的每个相应位。 每次比较可发现,两个1得到1,1和0得到1,两个0得到0.当我们观察数字的二进制表示时,很容易看出这一点。
11010110 // 214 | 01011100 // 92 -------- 11011110 // 222
To see the binary representation of a number, use the binary() function with println().
要查看数字的二进制表示,请使用binary() 函数和println()。
语法:
value | value2
参数:
value1 | int, char, byte |
---|---|
value2 | int, char, byte |
