If you don't want to wait on an (uncertain) inclusion into the Haskell standard, you can implement a small helper function to that effect yourself; essentially using encodeFloat .
Indeed, I have already implemented such a function. My gripe here is that it's extremely cumbersome to use such a function in a program, and it adds the possibily of programs crashing due to syntax errors at runtime. On 13:15 Mon 22 Feb , Simon Peyton-Jones wrote:
Or, alternatively, use quasiquoting

Ah, I was not aware of this feature. It does seem like a decent solution, in that it allows errors to be caught at compile time. Somewhat more verbose than I had hoped, but it's probably fine. Thanks. -- Nick Bowler, Elliptic Technologies (http://www.elliptictech.com/)
