Description |
Compares each corresponding bit in the binary representation of the values. For each comparison two 1's yield 1, 1 and 0 yield 0, and two 0's yield 0. This is easy to see when we look at the binary representation of numbers11010110 // 214 & 01011100 // 92 -------- 01010100 // 84 To see the binary representation of a number, use the binary() function with println(). |
