Examples include ``2e10``, ``-2e10``, ``2e-10``, ``2.5e1``. +Underscores can be used to separate digits of a numeric literal to aid readability. +For example, ``123_000``, ``0x2eff_abde``, ``1_233e34_89`` are all valid. Underscores are only allowed between two digits. + 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 |
