▶ USAGE Conventions relating to the use of the decimal point are confused. The IX GeneralConference on Weights and Measures resolved in 1948 that the decimal point shouldbe a point on the line or a comma, but not a centre dot. It also resolved that figurescould be grouped in threes about the decimal point, but that no point or comma shouldbe used for this purpose. These conventions are adopted in this dictionary. However,the Decimal Currency Board recommended that for sums of money the centre dot shouldbe used as the decimal point and that the comma should be used as the thousand marker.Moreover, in some countries the position is reversed, the comma being used as thedecimal point and the dot as the thousand marker
