Bitwise exponentiation
WebBinary exponentiation can be used to efficently compute x n m o d m x ^ n \mod m x n mod m. To do this, let's break down x n x ^ n x n into binary components. For example, 5 10 5 ^ {10} 5 10 = 5 101 0 2 5 ^ {1010_2} 5 101 0 2 = 5 8 ⋅ 5 2 5 ^ 8 \cdot 5 ^ 2 5 8 ⋅ 5 2. WebMar 10, 2024 · Maybe what we really need is a literal syntax for powers of two and not a dedicated exponentiation operator. And surprise: We already have such a syntax in the language with hexadecimal floating point literals with binary exponentiation 0x1pA reading as 1_16 * 2^(A_16) so 2^10 (n_b meaning n as interpreted to the base b). This syntax …
