Number of signs for an int variable?

**LoopString** · February 6th, 2010, 07:38 PM

Hello,

Is there any easy way to find out how many signs an int variable has please?

Example: 101 has three, -7 has one(two?), 1234 has four.

how about:

Code:

int CountSigns(int value)
{
    int length = value.ToString().Length;
    if(value < 0)
      lenght++;
    
    return length;
}

This might need a bit of tweaking (haven't tested it)

Code:

int number = -12345;
int charCount = Convert.ToString(number).Length;

Small enhancement possible...

Code:

int number = -12345;
int charCount = Convert.ToString(number, CultureInfo.InvariantCulture).Length;

I wonder whether it is really necessary. can an int have a different format in other cultures? I know a double can have a '.' or a ',' but an int is always the same, isn't it?
