#4381: scaleFloat does not handle overflow correctly.
---------------------------------+------------------------------------------
Reporter: draconx | Owner:
Type: bug | Status: new
Priority: normal | Component: libraries/base
Version: 6.12.3 | Keywords:
Testcase: | Blockedby:
Os: Unknown/Multiple | Blocking:
Architecture: Unknown/Multiple | Failure: Incorrect result at runtime
---------------------------------+------------------------------------------
If you call scaleFloat with a somewhat large integer value, the result
correctly overflows and yields Infinity. However, if you call scaleFloat
with an extremely large integer value, the result is finite!
{{{
> scaleFloat 30000 1
Infinity
> scaleFloat (maxBound :: Int) 1
0.5
}}}
