CASUALTY COMPUTATIONS

Does anyone know how the game computes casualties or perhaps more precisely stated, why does one end up with decimal point numbers?

At the very beginning of a game, a British cavalry regiment approached a French infantry square. They got to just within musket range and then stopped to think the whole thing over. While they reconsidered the French kept shooting, not effectively but they were slowly adding to the body count. The point total rose...5...7...8...10....

At that point the British decided it was Tea Time and turned to ride off. When the smoke cleared the French had racked up 17.7 points. No one was else was shooting as no one else had a line of sight to the British cavalry. I'm just wondering where the .7 came from? Did they shoot a horse? Or, since horses were valuable did they pop one of the officers?

The British are renowned for making rude gestures towards their enemies. These too slowly add up and the sheer number of them along with a little choreography might induce an enemy to leave in disgust. Not the most manly way of fighting, but there should be some small reward for driving the enemy away in this fashion, say 0.7.

ROTF!
