## usage

Conventions relating to the use of the decimal point are confused. The IX General Conference on Weights and Measures resolved in 1948 that the decimal point should be a point on the line or a comma, but not a centre dot. It also resolved that figures could be grouped in threes about the decimal point, but that no point or comma should be used for this purpose. These conventions are adopted in this dictionary.

Moreover, in some countries the position is reversed, the comma being used as the decimal point and the dot as the thousand marker
