Absolute function

So something like absolute(1000000000) doesn't return a magnitutide, but instead 1000000000. Am I doing something wrong?

Hello, kindly show us your blocks


abs Returns the absolute value of the given number. abs returned what it should. You might google absolute value to understand what a function like that returns. If a number is negative, it will return the positive value (the number times -1); if a number is positive, it will return the number.

See Math blocks


I was hoping it could return a mantra like javascript does.

Read the App Inventor documentation if you want to code using App Inventor; it is not javascript.

I made something like this that sort of works, but is resource heavy and slows down everything BY A LOT. Any ideas on how to optimize? Thanks!

Use the webviewer together with some Javascript, see an example here


What if I want to put the file with the app? I want to upload the file and have it there, as I don't think it will work if you keep a path. Thanks!

It's called a mantissa, not a mantra.

What does the "abs" procedure of your post #7 ?. Looking for the characteristic and the mantissa of a number?

upload it into the assets of your app, also known as media section in the designer


Logs it into a power of 10.

i.e. 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 = 1x10^100
