Unsure how to tell if an overflow is possible. I am given this sample code:
char x;
float f, g;
// some values get assigned to x and f here...
g = f + x;
Can someone please explain?
A
float, at its highest limits (binary exponent of 127), does not have sufficient precision (23 bits) to show a difference of the largest possiblechar(127, 7 bits), and so overflow is not possible since addition will have no effect (a precision of 127-7=120 would be required).
