Simple, reverse the string 12345.67 then convert the result to double. If you can do it for an int, you should be able to do it for a double.

Hello,

Try this:

C#

void Main()
{
    double d = 12345.67;
    Console.WriteLine("Reversed: {0}", ReverseNumber(d));
}

double ReverseNumber(double number)
{
    return double.Parse(ReverseString(number.ToString()));
}

string ReverseString( string s )
{
    char[] charArray = s.ToCharArray();
    Array.Reverse( charArray );
    return new string( charArray );
}

Cheers,
JAFC

Solution 1

Hi,

Try this:

C#

double d = 12345.67;
string reversedStr = new string(d.ToString().Reverse().ToArray());
double reversedDouble;
if (double.TryParse(reversedStr, out reversedDouble))
{
    // now, reversedDouble is the reversed double
}
else
{
    // unable to reverse the double
}

Hope this helps.
