According to C99, "When a finite value of real floating type is converted to an integer type other than _Bool, the fractional part is discarded (i.e., the value is truncated toward zero). If the value of the integral part cannot be represented by the integer type,the behavior is undefined." So, e.g., (long)x, where x is a double is in general undefined behavior without a range check. We have several cases in CPython where we need to fix this. |
