Thread: Crash my code

R handles these issues quite straightforwardly and sensibly using special numeric-type values "Inf" and, if you really screw up, "NaN" (Not a Number).

Code:

> 1/0
[1] Inf
> is.finite(1/0)
[1] FALSE
> -1/0
[1] -Inf
> 1/Inf
[1] 0
> 0/0
[1] NaN
> # although, amusingly:
> is.numeric(NaN)
[1] TRUE
