Lesson 2.0: Decimal Point

Symbols

decimal point

Explanation

A decimal point is a symbol used to separate the whole number portion from the portion whose value is less than a whole number. The braille representation of the decimal point reflects the symbol used in print - the period. The symbol is formed with dots two five six. There is no space between the decimal point and any numeral associated with it. The decimal point continues numeric mode, therefore the numeric indicator is not repeated after the decimal point. If there is no numeral to the left of the decimal point, it must be preceded by the numeric indicator.

When numerals with decimals are used with signs of operation or signs of comparison, follow spacing preferences for use of those signs. The numeric indicator is required before any numeral that follows a sign of operation or a space.
