2e2 = 2 x 2 = 4
2e3 = 2 x 2 x 2 = 8
2e4 = 2 x 2 x 2 x 2 = 16

OK, so back to the forum topic, we are saying there is no link then? Or is there one?
If it is to be it is up to me! |

There's no relevant link between the two cases.
The only thing that can be considered link is that Excel uses 16 bits to identify each row (allowing 65536 unique id's) and the screen uses 16 bits to identify each color (in fact 4 bits for red intensity, 4 bits for green, 4 bits for blue. Plus 4 bits for intensity/contrast. Hence RGB: red, green, blue)

So all we've learnt from this are that there are 10 types of people in the world, those who understand binary and those who don't. |

No, binary 1001001 is an odd number (decimal 73) - you can tell because it ends in a 1.
146 is 10010010 (128 + 16 + 2) |

@lowrida
"only 10 types of people". The 10 means two and not ten since it's binary representation.
So we can conclude that you are the type of people who don't understand binary.
@rojas
You still have a "No Go" for binary...
110011000101 =/= 3238
110011000101 === 3269
Ok. Binary class again:
1x2e11 + 1x2e10 + 0x2e7 + 0x2e7 + 1x2e7 + 1x2e6 + 0x2e7 + 0x2e7 + 0x2e7 + 1x2e2 + 0x2e7 + 1x2e0
= 2048 + 1024 + 0 + 0 + 128 + 64 + 0 + 0 + 0 + 4 + 0 + 1
= 3269
