How can I remove the last number from an integer?
Ex:
int value = 123456789;
int newValue = 12345678;
Note that the new value does not have 9.
I know it would be possible to switch to a string and use the substring(), but would like something without having to convert to string and then have to change again to int.

Pure mathematics:
123456789 / 10
How the value is integer is an automatic decimal rounding. If I was a guy with decimal places I’d have to do a little more math.
Behold working idenone. And in the .NET Fiddle. Also put on the Github for future reference.
Not that I care, just curiosity, what runs faster, turn into string and take everything but the last part, or do the math?
Mathematics always, with great difference, even if it was already string and didn’t need to convert, and need to, so it gets monster.
Okay, thank you very much.
Ual... simple and fantastic.
