Try intToFloat :: Int -> Float intToFloat n = fromInteger (toInteger n) -W-M- @ @ | \_/ On Fri, 28 Feb 2003, Mike T. Machenry wrote:
Hello,
I am having a problem. I recently desided I wanted a bunch function to return float instead of Int. I changed their type and wrote a new function that returned a float. I figured it'd be okay if all the others still returned Int since it's trivial to convert Int to Float. Sadly Haskell won't let me do this. What should I do? I attempted to cast all of the values in the functions that returned Int to Float, but I found no way to do this. I found fromInteger but it didn't seem to work on the return value of the cardinality function for instance. I guess cardinality much return Int. This is one of my functions.
smallestSet :: GameState -> Float smallestSet s = (-1 * cardinality (fLocations s))
This function is an error because it infer's an Int.
