Most programming languages have the ABS method, however there are some that do not
Whilst I have not used Ruby before, I am familiar its a framework that runs on PHP
The abs method is available on PHP

With Ruby the syntax appears slightly different is integer.abs

But for future reference the abs method is really small to code your self.
here is how in a few different languages:
JavaScript:
function my_abs(integer){
if (integer < 0){
return integer * -1;
}
return interger;
}
Python:
def my_abs(integer):
if (integer < 0):
return integer * -1
return integer
c:
int my_abs(int integer){
if (interger < 0){
return integer * -1;
}
return integer;
}
This means should you ever find yourself with a programming language that doesnt have a built in abs method, you know how to code your own its just simply multiply any negative number by -1 as you would of gathered in my examples
