So, I know this has been discussed before, but:
1/0 Infinity 0/0 NaN
... so I see from the archives that Infinity is mandated by ieee754 even though my intuition says both should be NaN.
Every other language throws an exception, even C will crash the program, so I'm guessing it's telling the processor / OS to turn these into signals, while GHC is turning that off. [...]
No, C will not, with floating point type. The following program prints out a string "inf\n". #include <stdio.h> int main (void) { double a=1, b=0; double i; i = a / b; printf ("%g\n",i); return 0; } I believe Haskell is behaving rationally. Cheers, Xiao-Yong -- c/* __o/* <\ * (__ */\ <
