Definition:Decimal Expansion/Size Less than 1

Definition

A number $x$ such that $\size x < 0$ has a units digit which is zero.

Such a number may be expressed either with or without the zero, for example:

$0 \cdotp 568$

or:

$\cdotp 568$

While both are commonplace, the form with the zero is less prone to the mistake where decimal point is missed when reading it.
