What's a good way to check if a double is an integer in C#? [duplicate]

Answer 1

If you want to check for an Integer, this will do it:

public bool IsInteger(double number)
{
    return (number % 1 == 0);
}

If you additionally want to check if the number could be converted into an Int32:

public bool IsInt32(double number)
{
    return (number % 1 == 0) && number >= Int32.MinValue && number <= Int32.MaxValue;
}
