[Lex Computer & Tech Group/LCTG] accuracy

[Steve Isenberg]

There reaches a point where accuracy is not practical.  It would have been
close enough for all practical purposes if Amazon rounded to 1 or 2 decimal
places.  This reminds me of a story.

A high school teacher was asked what "close enough for all practical
purposes" meant.  The teacher responded:
Suppose we take all of the boys and have them line up along one wall in the
gym, and have all girls line up along the opposite wall.  Draw a line
parallel to both the boy's and the girl's lines across the center of the
gym.
Then at a signal, both sides (boys and girls) advance halfway towards each
other, towards the center line in the gym.
At another signal, both sides again advance halfway to the center of the
gym.
Repeat this.
According to the Theory of Limits, the two lines will never meet.  But
after only a few advances, they will be close enough for all practical
purposes.
