Now use Abs() function in flash actionscript

Math.abs()

The flash Math.abs() method is used to return the absolute value of x. This basically means it returns the distance between 0 and x in flash actionscript. Although -5 is a negative number, it's absolute value is the same as 5. This is because -5 has a distance of 5 from x just as 5 has a distance of 5 from x. Example:

Math.abs(-10); // Returns 10 Math.abs(10); // Returns 10

Old Tutorial on Converting Negatives to Positive and Positive to Negative numbers

I needed to know the simples way to convert a number from positive to negative or negative to positive in actionscripts. Here it is:

// convert 100 to negative -100 n = 100; n = - n; trace(n);// will = -100 // convert -55 to positive 50 n = -50; n = - n; trace(n);// will = 50 This is how it work. Zero minus a positive number = a negative number. And Zero minus a negative number = a positive number.]]> http://newsourcemedia.com/blog/actionscript-converting-negitive-to-positive-numbers/feed/ 0
