Because your users are business folks wanting to know their advertising conversion rate, and none is available since there were no conversions, I would suggest: n/a By the way, as I see it, you're not giving them conversion rate per se. You're giving them cost per conversion, which should then...

Mathematically it's most certainly not infinity. if it was obtained from limit x^2/x as x -> 0, it should be 0, for instance. x/x^2 would give infinity, though. It's an indeterminate form, and in some sense more indeterminant than 1/0, 2/0 etc. In short, much more of your math would...

You should not be returning 0. You should return float.NegativeInfinity (if b is negative) or float.PositiveInfinity (if b is positive), and float.NaN if both a and b are 0. Note that this is the same behavior that you would get if you did this in your code: return a /...

The statement bottom % top yields a divide by zero error when top is zero. You can fix it by changing the first line of your simplify() method to this: if (top != 0 && bottom % top == 0) { ...

You can simply avoid this problem by using a continue statement: def f(x): return 1 / (exp(x) - 1) f_values = {} for i in range(-5,5): if i == 0: continue f_values[i] = f(i) print f_values >>> {1: 0.5819767068693265, 2: 0.15651764274966565, 3: 0.05239569649125595, 4: 0.01865736036377405, -2: -1.1565176427496657, -5: -1.0067836549063043, -4:...

You can disable the warning with numpy.seterr. Put this before the possible division by zero: np.seterr(divide='ignore') That'll disable zero division warnings globally. If you just want to disable them for a little bit, you can use numpy.errstate in a with clause: with np.errstate(divide='ignore'): # some code here ...

int a = 0; var b = 5/a; You are performing integer arithmetic here and so masking floating point exceptions has no effect on this expression. ...

When you calculate center point of an arc that is passing through 3 points, you definitely need to check if these points lies on the same line. But rewrite expression if (py2-py1)/(px2-px1) = (py3-py2)/(px3-px2) to avoid dividing Det = (py2-py1) * (px3-px2) - (py3-py2) * (px2-px1) if Det = 0...

Division by zero is undefined behaviour, see C11 standard 6.5.5#5 (final draft). Getting a trap or SIGFPE is just a courtesy of the CPU/OS. PowerPC as typical RISC CPU does not catch it, as it can safely be detected by a simple check of the divisor right before doing the...

The problem is that you're throwing an Exception that's undeclared in your method: Exception myException = new ArithmeticException("You can't divide by zero!"); throw myException; //here you throw Exception You can solve this by any of these: Declare that your method throws an Exception: void printResults(int a, int b) throws Exception...
