decimals have no soul
"Todd, buy me a thousand BJS at market!" I shouted across the room to our order entry operator extraordinaire and all-around good guy (these words don't begin to do Todd justice). A few seconds later, he would intone, "You bought a thousand BJS at sixty-five and seven sixteenths."
"Hey, what's the market on Weyerhauser?" someone would holler. "Fifty three at an eighth!" came the answer.
This is about romance, partly. Imperial measurements -- fractions -- are what I grew up with. My father would measure the area which would receive the copper gutter he was creating (for the home of, say, the Chairman of Gillette, the CEO of Tweeter, etc, or the former Ambassador to France.). He'd say something to himself like "Fourteen and a strong half," pronounced "hahf," in the Yankee way. He knew exactly how big "a strong hahf" needed to be.
But the romance ended. Someone, somewhere, decided that America had to toss in its lot with the Europeans (besides the British), who had decreed that all things must be decimal. Cold, precise, decimal. No margin for error. No room for interpretation. All things must be exact. Few things are, or course, though they try to make it so.
But it's more than romance. Fractions worked just fine.
One good thing about fractions is that they made communicating the decimal portion -- the fraction -- simplicity itself. When you said 'an eighth,' everyone knew that you were talking about the amount on the right side of the decimal. It was efficient. When you say 'twelve-point-five,' you're forced to ammend your message with 'cents' or some other tangential qualifier to indicate that you're not talking about whole dollars.
Now when you talk to an order entry person he says things like, "You bought a thousand at sixty-five SPOT forty three." Funny, I can't picture my father saying, "fourteen and a strong 5 centimeters." It's just too wordy.
Another trader has his own take on the romance angle. "If your wife asks how you did when you get home, and you say 'I made three-eighths,' it sounds like you made something. If you answer, 'I made thirty-seven and a half cents,' she thinks, 'Gee, I found that much in the couch cushions.'"
Markets have, heretofore, found a way to adapt to vain and frivolous rules imposed upon the business by the power players, because markets are made up of people. Regular, imperfect, motivated and live people.
Perfection is beyond the reach of man's hand, however finely he subdivides his observations. To err is human. To adapt is human. But decimals have no soul.
