What does the "abs" mean?

M_E___G_U_S_T_A

I just don't understand what the “abs” is in the block

mean. Can anybody help me please?

That takes the absolute value of the number in the parameters. The absolute value of a number always makes it positive. So if you put in a -4, the block would report a positive 4. If you put in a positive 4, it still would report positive. The rest of the options in the drop-down are advanced mathematical operations.

It returns the positive form of the given number.

ABS is the distance the number is from 0; it will always be positive. So abs (-9) = 9 and abs (9) = 9 because both of them are 9 away from 0.

Maybe this article can explain it better than us

Now I understand abs. But why is it important in scratch? In what possibilities can you use it in?

A simple example - you want to know the difference in the x coordinates of two sprites.

is easier than

If a negative number is put into the parameter, it's distance from 0 will be reported. Otherwise, the parameter will be reported.

Im kindoff confused about this. All i know is -9 converts into 9 positive

Please don't necropost.

Abs turns every negative number into positive.

-9001 = 9001.

ok, so look. the absolute value of… less say -a is equal to a. The absolute value of -a is a.

It's pretty much the number's distance from 0 on a number line

This thread was brought back by necroposting and I think the original question was answered so I'm closing this.
