二进制指算法

二进制指算法是一种利用一只或多只手的手指通过二进制来计数的指算法。如果一个人只用一只手的手指，他可以从0数到31，如果两只手都用的话，他可以从0数到1023，如果连两只脚的脚趾都用到的话，他可以从0数到1,048,575[1]。

  • 1 = 1

    1 = 1

  • 2 = 2

    2 = 2

  • 4 = 4

    4 = 4

  • 6 = 4 + 2

    6 = 4 + 2

  • 7 = 4 + 2 + 1

    7 = 4 + 2 + 1

  • 14 = 8 + 4 + 2

    14 = 8 + 4 + 2

  • 16 = 16

    16 = 16

  • 19 = 16 + 2 + 1

    19 = 16 + 2 + 1

  • 26 = 16 + 8 + 2

    26 = 16 + 8 + 2

  • 28 = 16 + 8 + 4

    28 = 16 + 8 + 4

  • 30 = 16 + 8 + 4 + 2

    30 = 16 + 8 + 4 + 2

  • 31 = 16 + 8 + 4 + 2 + 1

    31 = 16 + 8 + 4 + 2 + 1

  • 512 = 512

    512 = 512

  • 256 = 256

    256 = 256

  • 768 = 512 + 256

    768 = 512 + 256

  • 448 = 256 + 128 + 64

    448 = 256 + 128 + 64

  • 544 = 512 + 32

    544 = 512 + 32

  • 480 = 256 + 128 + 64 + 32

    480 = 256 + 128 + 64 + 32

  • 992 = 512 + 256 + 128 + 64 + 32

    992 = 512 + 256 + 128 + 64 + 32
