Scientific notation is also supported, where the base can have fractions, while the exponent cannot. Examples include ``2e10``, ``-2e10``, ``2e-10``, ``2.5e1``. +Underscores can be used to separate the digits of a numeric literal to aid readability. +For example, decimal ``123_000``, hexadecimal ``0x2eff_abde``, scientific decimal notation ``1_2e345_678`` are all valid. +Underscores are only allowed between two digits and only one consecutive underscore is allowed. +There is no additional semantic meaning added to a number literal containing underscores. + 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). This means that computations do not overflow and divisions do not truncate |
