Divide by zero and no error? [duplicate]

Answer 1

You may check like below

double total = 10.0;
double numberOf = 0.0;
var tot = total / numberOf;

// check for IsInfinity, IsPositiveInfinity,
// IsNegativeInfinity separately and take action appropriately if need be
if (double.IsInfinity(tot) || 
    double.IsPositiveInfinity(tot) || 
    double.IsNegativeInfinity(tot))
{
    ...
}
