Builtin Library
###############

The builtin library consists of a module containing a selection of constants,
methods and types that prove most useful in most circumstances. These are always
available from any scope in Jam.

Constants
=========

::

    const inf:Float

\

    The real number representation for infinity. Use ``-inf`` for negative
    infinity. Infinity can be the result of the value going outside of the
    supported range, or a zero division.

::

    const nan:Float

\

    The real number representation for not-a-number. NAN can occur for zero
    divisions like ``0/0``.

::

    const true:Bool

\

    A value of ``1`` for the `Bool` type.

::

    const false:Bool

\

    A value of ``0`` for the `Bool` type.

::

    const null

\

    A reference representing an object that is nothing. Actually provided by the
    language rather than the library, ``null`` can be
    :doc:`implicitly cast<../jam/type-casting>` to any
    :doc:`nullable type<../lib/builtins/types>`.
