Reviewing SQL and numbers
So you think you can count
Round and other functions
Instruction
Nice! Of course, SQL features numerical functions other than rounding too. Let's take a look at two of them.
The first one is abs(x) and it returns the absolute value of x. Positive numbers will be expressed as they are, but negative ones will be expressed without the minus at the beginning.
SELECT abs(3), abs(-3);
The above query will return 3 twice. The absolute value of 3 is 3, just like the absolute value of -3. Let's give it a try.
Exercise
For each character, show its stat_modifier and its absolute value (as absolute_value).
Stuck? Here's a hint!
Use abs(stat_modifier).
