.. _num-decimals:
Fractional looking integer literals
-----------------------------------
.. extension:: NumDecimals
:shortdesc: Enable support for 'fractional' integer literals.
:since: 7.8.1
Allow the use of floating-point literal syntax for integral types.
Haskell 2010 and Haskell 98 define floating literals with the syntax
``1.2e6``. These literals have the type ``Fractional a => a``.
The language extension :extension:`NumDecimals` allows you to also use the
floating literal syntax for instances of ``Integral``, and have values
like ``(1.2e6 :: Num a => a)``
