How can you get the first digit in an int (C#)?

Question

In C#, what\'s the best way to get the 1st digit in an int? The method I came up with is to turn the int into a string, find the 1st char of the string, then turn it back to

Answer 1

Here is a simpler way that does not involve looping

int number = 1234
int firstDigit = Math.Floor(number/(Math.Pow(10, number.ToString().length - 1))

That would give us 1234/Math.Pow(10, 4 - 1) = 1234/1000 = 1
