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 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). using them together with a non-literal expression).
