6.9.4. Fractional looking integer literals¶
- NumDecimals¶
- 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 NumDecimals allows you to also use the
floating literal syntax for instances of Integral, and have values
like (1.2e6 :: Num a => a)
