Checking individual digits in an integer

-----------------------------------

My Problem is...
I have to write a program that checks whether a number is the same when rotated 180 degrees. I don't need help with the coding, I would just like some assistance with understanding a command to do this. Is there a command that checks the character or digit at a specified location in an integer? eg.) What is the third digit of integer 1863? Thanks in advance.

I am using Turing 4.0.5.

Well an easy way would be turning it into a string, and then indexing the string.

a way to do it without converting to a string is integer division then mod by 10.  Look up the commands div and mod and think about how exactly you could do that

crossley's way it probably the better one, but just wanted to let you know there was multiple ways.
