WebOperators that have the same precedence are bound to their arguments in the direction of their associativity. For example, the expression a = b = c is parsed as a = (b = c), and not as (a = b) = c because of right-to-left associativity of assignment, but a + b - c is parsed (a + b) - c and not a + (b - c) because of left-to-right associativity ...

WebLeft and right shift moves the digits of a binary number to the left or to the right. For example: Decimal: 19 << 3 = 152 Binary: 0b00010011 << 3 = 0b1001100 Decimal: 19 >> 2 = 4 Binary: 0b10011 >> 2 = 0b00100 Note that when a bit is moved beyond the edges of a number, it just disappears. And when it's moved from an edge, it's zero.
