Reading Floats

[Simon Peyton-Jones]

It's a definite bug. It'll be fixed in 6.02.  Thanks for reporting it.

| Hi,
| 
| I recently encountered something I found a bit peculiar when reading
| floats from strings.  Leading zeroes seem okay, as long as there is no
| decimal point.  To wit:
| 
|         Main> (map read ["1.0", "00000", "01", "01.0"]) :: [Float]
|         [1.0,0.0,1.0,*** Exception: Prelude.read: no parse
| 
| Neither is leading decimal point allowed:
| 
|         Main> (read ".01") :: Float
|         *** Exception: Prelude.read: no parse
| 
| Is this how it's supposed to be?

| If I haven't seen further, it is by standing in the footprints of
giants
