Decimal fraction literals are formed by a ``.`` with at least one number on one side. Examples include ``1.``, ``.1`` and ``1.3``. +Scientific notation is also supported, where the base can have fractions, while the exponent cannot. +Examples include ``2e10``, ``-2e10``, ``2e-10``, ``2.5e1``. + Number literal expressions retain arbitrary precision until they are converted to a non-literal type (i.e. by using them together with a non-literal expression).
