A number placed next to the decimal point on the right indicates the number of tenths to be taken, if two places from the decimal point it indicates hundredths, if three places from the decimal point it indicate^ thousandths and the same system is carried out to any extent.

If a single figure is written, without any decimal point next it, it expresses the number of units. If a single figure is to express tens, hundreds or other decimal product, ciphers are used to indicate its position, which are placed to its right; if a single figure is to express a decimal fraction, ciphers on its left fix its position with reference to the decimal point.

A number placed next to the decimal point on right indicates tenths; placed next to the decimal point on the left, it indicates units. This is inconsistent and suggests that the proper place for the decimal point would be where units are placed. This of course is not practical; logic has to yield to practicability.
