### Base-10 bigot

Feb. 13th, 2007 07:27 amI'm done reading

*Code*now, and the book club at work is beginning to move into the book we're really covering. Near the end,

*Code*was covering binary-coded decimal numbers, which meant talking first about binary numbers that fall between integers. These work about the way you might imagine -- the numbers after the dot represent negative powers of 2 instead of negative powers of 10. So, 1.1 in binary is 1.5 in decimal; 0.11 is 0.75 in decimal, and so forth.

That dot is referred to as a binary point. And I honestly thought it was a typo.

*What? There's nothing inherently base-10 about the term decimal point*, I thought. Hello, does the "dec" in "decimal" mean nothing to you?

The Numerical Relations office is probably going to send me off to sensitivity training if they ever get wind of this.
