# Arithmetic/Reading Decimal Numerals

From Wikibooks, open books for an open world

The word *and* is used only for the decimal point; *And* is also used to separate a whole number and a fraction. A comma is used at every third place, starting at the decimal point and moving left.^{[1]}^{[2]} Frequently a comma or space is used at every third place moving to the right of the decimal point.

Additionally, no comma is used before *and*. Also, all decimals end in ths except unitary decimals that end in th.

Alternatively, you may say the whole number, followed by a *Point* and the digits of the decimals from leftmost to right. This is a much more natural and informal way of saying numbers.
