How do I handle floats?

I want to add float numbers in my calculation, but I don't understand why I'm getting different results than my calculator:

Browser.alert(float(4.8)*6) gives me 28.79999999 rather than 28.8

see example in screenshot

I guess by default javascript converts numbers into text with as many decimal places as possible.

The browser console typing 4.8*6 gives 28.799999999999997

when you use the str expression you get the same: str(4.8*6) -> 28.799999999999997

But fun fact, if you just try setting text without str construct rounds it slightly to give cleaner values.

AKA set text to 4.8*6 gives 28.8

Anyways, that subtlety isn't worth keeping track of. You can use the roundToDp to round to a number of decimal places so the text looks cleaner.

roundToDp(4.8*6, 10) -> 28.8

Thank you for the answer and thank you for all the work you do for the community
